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.
