Starting Monday morning, 27 November, this site will be down for a major upgrade. RVWeather.com 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.
From the RV Weather Summer Office in Moose Wyoming:
These are the most significant weather impacts to RV travel over the next two to three days. I do not list every area of rain, showers, or breezy winds. (It would be exhausting for both of us!). Please check out the animations and graphics for a good depiction of the weather along your route.

Flooding is already occurring in this region and an additional 5-10 inches of rain may fall in the next three days. If you are camping by any small river, stream, creek, or pond, be very careful regarding rising water levels. Leave low-lying elevations before roads flood and you are cut off. Do not drive or tow through flooded roadways. If you are in a Flash Flood Warning – seek higher ground immediately. I-26, I-40, I-77, I-81 (VA), I-85 potentially impacted.

— Southern GA; FL: Strong to possibly severe thunderstorms today and again on Wednesday. Isolated damaging winds possible. I-4, I-10, I-75, I-95 potentially impacted.
— Tropical Storm Bret formed yesterday over the central Atlantic and is moving west. The storm should reach the eastern Caribbean Islands by Thursday, likely at hurricane strength. A lot of questions, as to where Bret goes, and how strong it will be, from there. RV’ers along the Gulf and Southeast Coasts should monitor this system. It is FAR too early to where, or even if, there will be any impacts to the continental U.S. I would not change any travel plans at this time.
— There is a second tropical disturbance to the east of Bret that now has a high chance of also developing into a Tropical Storm. If it does, it will be named Cindy. Probably a similar track to Bret, so we’ll watch this system as well.
