High Wind Event With Coastal Flooding Concerns Sunday Night

Not only we have to deal with some heavy rainfall, a little bit of snow for the northern areas of Delmarva and the Maryland Western Shore. There’s an event that is sleeping under the radar that has my full attention. When that low starts dropping below 990mb, that low level jet stream is very strong being pulled into this surface low.

70-80kt Winds at 850mb ( Low Level Jet)

Anytime I start seeing winds at 5000ft getting over 60kts, I get a bit uneasy in the damaging wind department. This is a long fetch stream of onshore winds we are talking about from the Gulf Stream. There is going to be a lot of wind energy pushing on the east side of this low. And it’s all onshore flow too. There’s more issues with this as well.

Winds at the surface are showing widespread wind gusts of 40-60 mph from the east and southeast. Another problem surfaces as well. We have a high tide cycle that’s expected during the evening hours Sunday Night. To add more salt in the wound, this weekend is a full moon as well. So take 40-60mph surface winds, plus onshore flow, plus a high tide cycle, and a full moon, it’s not going to be a fun time for a coastal locations this weekend. Strongest winds appear to be in a window from 8pm Sunday until 4am Monday.

Already a few tidal forecast in the region showing Moderate Flood Stage forecasts like this one in Crisfield. So we really got to watch our coastal regions Sunday night for flooding concerns.
