2022 Hurricane Season
#1
La Nina should weaken the latest hurricane in the eastern Pacific:

Hurricane Darby's expected turn toward the west-northwest will have critical implications for its future and how close the hurricane will venture to Hawaii.
But a more northern track in the Eastern and Central Pacific means Darby will approach waters that are too cool to sustain a hurricane or tropical storm, as well as strong upper-level winds that are not conducive for strengthening.
Forecasters expect Darby to start feeling the effects of the more hostile environment by Wednesday, and the system could weaken back into a tropical storm by Thursday over cooler waters.
Darby is expected to still be about 900 miles east of Hawaii by the end of the workweek.
Forecast models show a continued deterioration of the system’s structure and organization beyond the forecast cone.
The cooler-than-average waters in parts of the Central Pacific and the increased upper-level winds are classic products of a La Niña that is in control of weather patterns.

The positive side of climate change = bigger hurricane = bigger wave

Was bigger during hurricane Iniki back in 1992 though.

The swell that caused the big waves didn't come from the hurricane. The large waves were from a winter storm in the south pacific.

Thanks Obie.
I read this last week: "Large swells generated by Darby are expected to affect portions of the Hawaiian Islands over the weekend," the National Hurricane Center (NHC) wrote on Friday. 

The County of Hawaii also closed parks over the weekend due to anticipated swells from Darby, but as you noted and NOAA reported, the big waves actually originated in the South Pacific.


The next storm is Estelle currently near Mexico:
NHC said little change in strength is expected through Tuesday, but a steady weakening is then expected to follow for the next few days.

Hurricane-force winds extend outward up to 25 miles from the center, while tropical-storm-force winds extend outward up to 105 miles.
