December 3, 2019 (San Diego’s East County) – Thunderstorms Wednesday is expected to bring moderate to heavy rainfall and lightning strikes to our region. Bursts of moderate to heavy rain will raise the threat for street flooding in areas with poor drainage or low lying areas prone to flooding. Rain falling on snow covered or frozen ground could also lead to enhanced runoff and localized flooding in the mountains.
Waterspouts are possible over coastal waters and the National Weather Service’s Skywarn activation may be requested on Wednesday. Surf could reach nine feet along San Diego’s coastline.
Storm total rainfall is forecast to be 0.50 to 1 inch in the coastal and valleys zones, and from 1 to 2.5 inches in the mountains. The deserts will come in mostly less than 0.50 inch. Snow levels will drop to 6,000 feet by Wednesday night.
South winds from 15-25 mph Wednesday morning are likely from the coastal waters into the inland valleys. Mountain and deserts winds will increase to 20 to 30 mph with gusts to 50 mph.
Dry weather is forecast for Thursday and Friday, though light showers may fall over the weekend, the National Weather Service reports.
