Hope everyone is prepared and stays safe. It will be interesting to see what our mountains do to the hurricane's path. I don't want it to slow down and linger, but it would be awesome if wind challenges mountain and loses. Maybe fire and water can sit this one out?

HURRICANE ISELLE DISCUSSION NUMBER 30
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI EP092014
500 AM HST THU AUG 07 2014
ALTHOUGH THE SATELLITE PRESENTATION OF ISELLE HAS DEGRADED SLIGHTLY
OVER THE PAST COUPLE OF HOURS...A PERSISTENT EYE FEATURE CONTINUES
TO BE OBSERVED...AND ISELLE REMAINS A HURRICANE. DATA FROM AN AIR
FORCE RECONNAISSANCE AIRCRAFT CORROBORATE THE SLIGHT WEAKENING
TREND OBSERVED BY SATELLITE...AS MAXIMUM FLIGHT LEVEL WINDS IN THE
NORTHEAST QUADRANT DIMINISHED FROM 100 KT TO 85 KT OVERNIGHT...AND
MAXIMUM SFMR WINDS HAVE LOWERED TO NEAR 60 KT. BASED ON A BLEND OF
THE AIRCRAFT DATA AND SATELLITE INTENSITY ESTIMATES BETWEEN 4.0/65
KT AND 4.5/77 KT...THE INITIAL INTENSITY OF ISELLE IS BEING LOWERED
TO 70 KT FOR THIS ADVISORY.
INITIAL MOTION ESTIMATE IS 285/15 KT...WHICH HAS BEEN FAIRLY
CONSISTENT OVER THE PAST 12 HOURS...WITH ISELLE BEING STEERED BY A
MID LEVEL RIDGE TO THE NORTH. THE UPDATED FORECAST TRACK REMAINS
CONSISTENT WITH THE LAST SEVERAL FORECASTS IN THE SHORT TERM...AND
REMAINS IN GOOD AGREEMENT WITH THE MULTI-MODEL CONSENSUS...WHICH HAS
BEEN CONSISTENT IN DEPICTING LANDFALL ALONG WINDWARD BIG ISLAND
THIS EVENING. IN 36 TO 48 HOURS ISELLE IS EXPECTED TO REACH THE
WESTERN PERIPHERY OF THE RIDGE AS A WEAK CUT OFF LOW DIGS SOUTHWARD
ALONG THE FORECAST TRACK...RESULTING IN A SLOWING OF THE FORWARD
MOTION THROUGH 72 HOURS. AS THE LOW MOVES SOUTH AND ISELLE WEAKENS...
A NEW RIDGE ALOFT IS FORECAST TO BUILD NORTH OF THE WEAKENING
ISELLE...AND THE FORWARD MOTION WILL INCREASE ONCE AGAIN. THE
UPDATED FORECAST TRACK ONLY OFFERS MINOR CHANGES TO THE PREVIOUS...
AND CLOSELY FOLLOWS THE WELL-PERFORMING CONSENSUS TVCN.
THE INTENSITY FORECAST CALLS FOR ONLY SLIGHT WEAKENING BEFORE
LANDFALL TONIGHT...DESPITE THE FORECAST OF MODERATE NORTHWESTERLY
SHEAR BY SHIPS GUIDANCE. ISELLE REMAINS SOUTH OF A RIDGE ALOFT
CENTERED WEST OF THE MAIN HAWAIIAN ISLANDS AND A RIDGE CENTERED OVER
THE BAJA PENINSULA. A COL...OR WEAKNESS...BETWEEN THESE TWO RIDGES
PROVIDES A LIGHTER SHEAR ENVIRONMENT IN WHICH ISELLE WOULD BE ABLE
TO MAINTAIN THE CURRENT INTENSITY BEFORE LANDFALL...WHEREAS IF
ISELLE WERE TO MOVE WEST OF THE COL AND CLOSER TO THE RIDGE CENTERED
TO THE WEST...THE SHEAR PROFILE WOULD BE MORE DEBILITATING. THE
INTENSITY FORECAST PROBLEM IS THAT GLOBAL MODELS ARE OFFERING
DIFFERENT SOLUTIONS AS TO THE INTERACTION BETWEEN ISELLE AND THE
FLOW ALOFT IN THE SHORT TERM...WITH SOME SOLUTIONS TRACKING ISELLE
AND THE COL WESTWARD IN TANDEM...WHILE OTHERS MOVE ISELLE WEST OF
THE COL AND INTO AN AREA OF STRONGER SHEAR. INTERACTION WITH THE
TERRAIN OF THE BIG ISLAND IS EXPECTED TO WEAKEN ISELLE TONIGHT...
WHILE A SOUTHWARD-MOVING CUT OFF LOW DEVELOPING NORTHWEST OF THE
HAWAIIAN ISLANDS ON DAYS 2 AND 3 WILL BRING STRONGER SHEAR.
INTERACTION WITH THIS LOW IS EXPECTED TO LEAD TO THE DEMISE OF
ISELLE...WITH REMNANT LOW STATUS FORECAST BY DAY 5...CLOSELY
FOLLOWING THE TRENDS OFFERED BY THE SHIPS GUIDANCE.

Just put your stuff in the front yard, and Iselle will blow it to the dump for you. [

Yeah if it's a cat 1 you guys will be OK as long as it keeps moving at a good clip. Properly constructed metal roofs tend to fare better than asphalt shingle too.
We had a cat 1 that was moving real slow. I didn't lose any shingles but it ground at my roof so long it washed most of the sand off what was supposed to be very extended life shingles. Of course the next hurricane took a bunch of shingles so in the end I guess it didn't matter. I did learn that insurance will pay for the roof if the shingles are blown off but not if they are just ruined, resulting in needing a new roof.

hang on everyone. be safe. you are all in my prayers.
RE: 5am update (Thursday) - birchl - 08-07-2014
insurance? shingle roofs? you do realize that we are talking sheets of corrugated tin, banged together shacks, tarpaulin tents and canopies, and sheet plastic greenhouses? my little cabin actually has hurricane ties, and possibly so do some of the 'proper' houses in the town. for the most part though these buildings are held together with aloha

Seems like the wind is starting to pick up a little. Getting a few gusts sway the trees here in Leilani. (8:30am)
