philosophy here at Chunkhaus is to prepare for the worst and be relieved… if it doesn't happen.

Iʻve spent the last two days reading the charts to see if I need to bring in all the gardening pots, mixtures and debris thatʻs accumulated on our lanai since Douglas in 2020. I finally decided Iʻm spending more time worrying about it than actually just doing it. So I did it. Now I can relax a little bit. Let it blow let it blow let it blow. But not too hard please.

A Tropical Storm Warning has been issued for... * Hawaii County SUMMARY OF WATCHES AND WARNINGS IN EFFECT... A Tropical Storm Warning is in effect for... * Hawaii County A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere in Hawaii should monitor the progress of Calvin. For storm information specific to your area, please monitor products issued by the National Weather Service office in Honolulu Hawaii. DISCUSSION AND OUTLOOK ---------------------- At 500 PM HST (0300 UTC), the center of Tropical Storm Calvin was located near latitude 17.4 North, longitude 145.4 West. Calvin is moving toward the west near 22 mph (35 km/h) and this motion is expected to continue over the next several days. On the forecast track, tropical storm conditions are expected over Hawaii County starting Tuesday night. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Calvin is forecast to gradually weaken during the next several days. Tropical-storm-force winds extend outward up to 105 miles (165 km) from the center. The estimated minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Calvin can be found in the Tropical Cyclone Discussion under AWIPS header TCDCP1 and WMO header WTPA41 PHFO. and on the web at hurricanes.gov/text/HFOTCDCP1.shtml WIND: Tropical storm conditions expected within the warning area starting Tuesday night. RAINFALL: From Tuesday night into Thursday, storm total rainfall amounts of 4-8 inches, with maximum amounts of 10 inches are possible, mainly along the windward areas of the Big Island of Hawaii. Storm total rainfall amounts of 1-4 inches are expected elsewhere in the state. This rainfall could lead to localized flash flooding and mudslides. SURF: Swells generated by Calvin are expected to begin reaching the main Hawaiian Islands during the next couple of days. A rapid increase in surf is expected Tuesday and Wednesday. This surf will likely cause life-threatening surf along exposed east-facing shores. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 800 PM HST. Next complete advisory at 1100 PM HST. $$ Forecaster Kodama  (07-17-2023, 06:24 PM)MyManao Wrote:(07-17-2023, 05:27 AM)HereOnThePrimalEdge Wrote: I’m not a proponent of Maunas vs Hurricane, with the Maunas always victorious.. You forget to mention that although Iselle did indeed jink a little to the south as it approached the island, it then jinked back to the north, i.e., while it was still offshore towards the mountains. It then crossed the island, not south of it, and remained a tropical storm until it had passed south of Oahu. The evidence doesn't support your conclusions. Take typical trade wind weather. That piles up rain clouds against Mauna Kea and Mauna Loa. The mountains don't magically redirect them around the island, they just keep on coming. Why would the mountains have a different effect on tropical storms or hurricanes?
8pm update clarifies the winds up a bit:

Calvin will weaken as it moves westward to the south of the other Hawaiian Islands Wednesday and Wednesday night, bringing the potential for some peripheral impacts. Primary impacts are expected on the Big Island, with a period of heavy rainfall, high surf along east facing shores, and locally strong wind gusts. Flooding rain will be possible as early as Tuesday evening on the Big Island, with chances for heavy rain expected to increase for much of the state Tuesday night and Wednesday. Expect storm total rainfall of 4 to 8 inches across mainly windward portions of the Big Island, with around 1 to 4 inches of rainfall elsewhere across the state. Coastal impacts associated with Calvin will include rapidly building surf Tuesday night through Wednesday. Surf heights will reach High Surf Advisory levels for most windward coasts, with High Surf Warning levels (greater than 15 feet) along east facing shores of the Big Island. Although peak surf heights on the Big Island will likely occur around low tide Wednesday morning, some minor overwash and erosion is possible for exposed low-lying coastal areas. Locally strong winds may begin as early as Tuesday evening across parts of the Big Island, with north winds shifting to the northeast and east as Calvin moves westward. Winds will primarily be northeasterly over the smaller islands, strongest Wednesday and Wednesday night. It is important to note that the mountainous terrain of the islands can produce localized areas of enhanced winds, even well away from the tropical cyclone center. POTENTIAL IMPACTS ----------------- * WIND: Prepare for hazardous wind having possible limited impacts across the Hawaiian islands. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. * SURGE: Prepare for locally hazardous surge having possible limited impacts across portions of windward and southeast Big Island. Potential impacts in this area include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. Elsewhere across the Hawaiian islands, little to no impact is anticipated. * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts across mainly windward and southeastern portions of the Big Island. Potential impacts include: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, arroyos, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. Prepare for locally hazardous rainfall flooding having possible limited impacts across other Hawaiian Islands from Kauai to Maui. * TORNADOES: Prepare for a tornado event having possible limited impacts across the Hawaiian islands. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Honolulu HI around 11 PM HST, or sooner if conditions warrant.  SITUATION OVERVIEW ------------------ The center of Tropical Storm Calvin is forecast to pass over, or just south of, the Big Island of Hawaii tonight and early Wednesday, then pass well south of the other Hawaiian Islands through Wednesday night. This places the islands in the windier and wetter part of Calvin`s circulation. Impacts are expected to be greatest on the Big Island, but strong and gusty winds, locally heavy rainfall and high surf along east facing shores can be expected statewide. Heavy rainfall will likely begin this evening on the Big Island, with chances for heavy rain increasing elsewhere across through Wednesday as Calvin moves steadily toward the west. Expect storm total rainfall of 4 to 8 inches across mainly windward portions of the Big Island, with around 1 to 4 inches of rainfall elsewhere across the state. Coastal impacts associated with Calvin will include rapidly building surf tonight through Wednesday. Surf may reach as high as 15 feet along east facing shores of the Big Island, and up to 10 feet along east facing shores of the other islands. Although peak surf heights on the Big Island will likely occur around low tide Wednesday morning, some minor overwash and erosion is possible for exposed low-lying coastal areas. Locally strong winds are likely to begin this evening over the Big Island, with north winds shifting to the northeast and east as Calvin moves westward through Wednesday morning. Winds will primarily be northeasterly over the smaller islands, strongest Wednesday and Wednesday night. It is important to note that the mountainous terrain of the islands can produce localized areas of enhanced winds, even well away from the tropical cyclone center. POTENTIAL IMPACTS ----------------- * WIND: Protect against hazardous wind having possible limited impacts across the Hawaiian islands. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. * SURGE: Protect against locally hazardous surge having possible limited impacts across portions of windward and southeast Big Island. Potential impacts in this area include: - Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. - Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. - Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. - Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings.

PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- Now is the time to complete necessary actions to protect your family and secure your home or business, prior to the onset of tropical storm conditions tonight. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes can extend well away from the center of the storm. Keep cell phones well charged as localized power outages are possible. NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Honolulu HI around 11 AM HST, or sooner if conditions warrant. PUNA WEATHER GROUP: Tuesday 18th July 2023 (5am post) Warm and humid with little or no rain most of the day today. Winds calm, but with bursts of gusty at times... in general a pretty odd day as it's the "calm before the storm". Tonight some showers, possibly very heavy at times, but the main event is likely to be from 11pm tonight to 3am Wednesday with intense rain and strong gusts winds. Some thunder is also possible, maybe even an isolated tornado. Conditions improve by daybreak on Wednesday with much less rain and wind, but very muggy... ick. Power could be out at your home when you wake up... so plan accordingly. --- Slightly warming sea surface temperatures between Calvin and our island allows Calvin to maintain its strength as it approaches our island tonight. Shear remains around 10mph from the south or southeast, keeping the strongest activity north of the center. The center of Calvin is likely to track over, or just south of Kau, but this should spare them the strongest impacts. Areas from Pahoa north to our Hamakua coast are right in the bullseye. In the satellite loop Calvin's low level circulation remains symmetrical with a distinct center. Spiral banding to the south of the center is indicative of dry air working its way into the storm. The sustained convection to the north of the center is likely to work its way to the northwest of the center as the storm approaches, and this pushes the time of arrival of the heaviest activity forward an hour or so. It also means the activity is likely to end a little sooner. Calvin is moving a little faster, now 22mph. That also means that activity starts and ends a little sooner. It also means that winds could be a little higher. The winds are calculated by adding the spinning winds around the storm to the forward speed of the storm, so maybe some gusts will approach 60mph around midnight or so.

The NOAA daily Hilo forecast doesn't sound TOO bad.
Edit: Updated forecast for tonight: Showers and possibly a thunderstorm. Some of the storms could produce heavy rainfall. Low around 71. Windy, with a north wind 14 to 19 mph becoming east 21 to 26 mph after midnight. Winds could gust as high as 38 mph. Chance of precipitation is 100%. New rainfall amounts between 3 and 4 inches possible
Here is a great GOES animation loop. You can watch as Calvin approaches and see what he's doing as we go through this. Looking like a stormy windy night to me! (other weather resources are saying possible gusts to 60 mph late tonight early AM, if so, not good)

Yes. Right now it looks like that could occur along the Kapoho-Kalapana coast, and up around Hawi. |
