The following is a briefing from the National Weather Service Baltimore/Washington as of 10 AM Wednesday morning:
Threats:
• Heavy Rainfall and Flash Flooding, Tonight into Saturday.
• Severe storm and tornado threat this afternoon/evening.
Overview and Impacts:
• Severe flooding possible. Most likely Thursday into Friday.
• A powerful storm will linger over the Midwest the next several days.
• As with any case that involves localized banding of rain, the exact location of the highest totals is difficult to pinpoint at this time, but will likely be across our region.
• Now thru Friday: 3-6" expected, but up to a foot is possible in localized areas.
• Greatest threat: Maryland, northern Virginia (including the Washington and Baltimore metros),& eastern panhandle of West Virginia. A Flash Flood Watch has been issued for this area.
• Amounts have already approached 5" in one location in southern Maryland this A.M., indicating the potential with this storm the next couple of days. These amounts could cause flooding despite dry conditions.
Also: Areas east of the Blue Ridge Mountains and the DC Metro Area southward have been upgraded to a Slight Risk of severe thunderstorms this afternoon and evening. The main severe threat is strong wind gusts, although there is also a risk of a brief tornado.
