Starting Monday morning, 27 November, this site will be down for a major upgrade. will return no later than Wednesday 29 November — sooner if possible. When the site returns, WILMA, our NEW(!) integrated weather impacts product, will be available. The Paywall will also be implemented. RV Weather will continue to provide free access to essential, RV-relevant National Weather Service Warnings and Advisories, current weather, and weather safety information. While the main site is off-line, I will post a simple forecast to my email list and to RVWeather on Facebook.

Happy Summer Solstice! Enjoy the longest day(light) of the year!

Tropical Storm Bret is in the Caribbean Sea and continues to weaken. It will dissipate this weekend south of Jamaica. No threat to the continental U.S.

Tropical Storm Cindy strengthened slightly overnight. It is now about 600 miles east of the eastern Caribbean islands and is moving to the west-northwest. Maximum sustained winds are 60 mph. Cindy is expected to dissipate by the middle of next week between the Bahamas and Bermuda. There is a chance the storm will re-strengthen once it reaches Bermuda, but even if that happens it should pose no threat to the U.S. Mainland. We’ll monitor this system. No need to change any RV or travel plans.
