About HawaiiStorm
HawaiiStorm was built by Mariano Crivello to put everything you need to make good decisions during storm season in one place.
Why it exists
I built the first version about a week before Hurricane Lowell hit us here on Kauai. Then, eight hours before the storm arrived, we lost our radar. Because we still had the rest of this data, we could prepare for a Category 2 storm hitting the island, rather than going only by what the NHC was saying. For days before it arrived, the Navy's model consistently showed the storm hitting the island.
Now I'm ready to share it. My hope is that it helps others, and that it adds some redundancy for when things go bad. When one source goes dark, the others are still here.
What it brings together
- National Hurricane Center and Central Pacific Hurricane Center advisories: the cone, the track and the wind radii
- National Weather Service Honolulu alerts, island by island
- Model guidance: the ensembles and the named models, including the Navy's NAVGEM and COAMPS-TC, next to the official forecast
- Buoys, tide gauges and conditions on each island
- GOES-18 satellite imagery, and hurricane hunter flights in 3D
Not an official source
Nothing here is an official forecast. For life-safety decisions follow the National Weather Service in Honolulu (opens in a new tab), the Central Pacific Hurricane Center (opens in a new tab) and your county emergency management agency.
