What was once Tropical Storm Bertha has weakened and dropped to Tropical Depression status and will shortly be a remnant low formerly known as Bertha. The impact to the Commonwealth will be anywhere from 1 – 3” of rain. Flooding will be a major concern as the region is already saturated from last weeks rainfall so any rain will run off quickly. Flash Flooding is likely in some of our mountainous regions overnight. Areas that got hit especially hard on Monday like Henry, Franklin and Roanoke counties will be impacted once again. The good news with this event is that it will be a fast mover, but the bad news is that there will be much more overpowering rain. Stay alert for rising and swift moving water tonight and tomorrow morning. Since this is a storm of tropical origin, I also expect to see some gusty winds. The potential for power outages as trees get blown over by the wind is fairly high.
Thursday will see the rain ending early but some spotty storms and showers will linger off and on into the afternoon. The rain that falls with these cells will be impressive so very localized flooding may occur, especially creeks, streams and urban areas. As the region heats up, there is a greater chance for strong thunderstorms to ignite and gusty winds so more issues with downed trees may arise.
More rain is on the way on Friday and Saturday as another batch of moisture moves in from the west and south. There will be an area of High Pressure drifting over the western Atlantic helping to slow the eastward movement of the rain and keep the Mid Atlantic region in a period of rain and some storms into Saturday. The flooding needless to say will be likely on the saturated soils.
Sunday will be the beginning of an extended period of dry weather that will be very welcomed and needed. The temperatures from Sunday to Monday will be a bit cooler than normal, reaching the middle 70s. We are expecting to start the meteorological summer (June, July and August) on a dry note.
June 1st is also the official start of the Atlantic Hurricane season, but as you know, we already have seen two named storms. Hopefully this is not a sign that we are going to be very active this year.
Stay Safe and healthy.
