Central Pacific

The following maps are from the Central Pacific Hurricane Center (CPHC), co-located with the National Weather Service Forecast Office, in Honolulu Hawaii. According to the CPHC, it “issues tropical cyclone warnings, watches, advisories, discussions, and statements for tropical cyclones between 140 Degrees West Longitude to the International Dateline”. If you live in or travel to Hawaii, this is the area to watch.

2019 Hurricane Season

The hurricane season officially starts June 1st and ends on November 30th, but tropical storms can form at any time if conditions are right. Climate change is basically extending the season. However, about 95 percent of storms are produced during the two-and-a-half months of the season’s peak, from mid-August to late October.

NOAA and the National Hurricane Center provide this great chart showing the frequency of tropical storms and hurricanes over the past 100 years.

My FAV Weather Sites

I am listing the links that I visit the most often to get the latest tropical weather information and forecasts. You should watch your local weather forecasters as well to stay alert to specific threats to your location. The sites below are giving you the larger picture. Hurricanes and tropical storms are giant weather systems, but they can reach down to create very specific local damage.

National Hurricane Center – Official forecasts

Tropical Tidbits blog (and videos) – Levi Cowen explains the global and big picture weather patterns and fronts that steer these massive storms. This is actually very calming, as he doesn’t hype up what is happening. He posts to the blog and also has great videos explaining active tropical forecasts on his Tropical Tidbits YouTube channel as well.

Mike’s Weather Page – This website packs a tremendous amount of tropical weather maps, satellite imagery, and radar data. Mike is also from Florida, though we have not yet met. I follow his blog almost every day.

South Florida Water Management District model map – other high quality maps

Tropicals Tidbits GFS model – map is in a player to show potential paths of storms

Tropical Tidbits ECMWF model – map of this top European model also in a player

NASA Hurricane & Typhoon Blog – A scientific spin on the latest storms. No Hype. Often has the latest in remote sensing.
