Cold Front Brings Flood Threat

21 Sep 2021, 6:47 pm

Flood Alerts have been issued for a few areas across the Eastern tier of the United States through Thursday for heavy rain that will lead to additional flooding over the next couple of days.

Great Lakes Region

Flood Alerts

A Flood Watch has been issued through Thursday morning for portions of southeast Michigan and into Indiana and Ohio as a cold front has been moving through and will stall overnight through Wednesday.

Those that live in flood prone areas should be prepared to take action if flooding develops.

Forecast Rainfall Totals

Our In-house forecast has been consistently putting out rainfall totals up to 3-5″ in some localized spots.

Forecast Timing

Rain has already started across these areas and will continue overnight tonight and into the next few days as shown by our forecast. Training rain over the same areas will also oversaturate a lot of these regions too.

Central Appalachia

Flood Alerts

Flash Flood Watches have been issued through Wednesday morning for the Appalachia region as deep tropical moisture moves through overnight. Into the Blue Ridge mountains a bit of upslope flow in the higher terrain will help to increase the rainfall intensity and the amount of rainfall too.

Forecast Rainfall

Here’s a look at what our forecast model is expecting in terms of rainfall totals. 3-5″ of widespread rain will be likely, with localized amount that could exceed those totals especially into the Mountain ridges.

Forecast Model

The same front will bring rain through the Central Appalachia region. Meanwhile, some onshore flow off the Atlantic Coast states has been pushing rainfall and moisture inland for most of the day on Tuesday and will continue to team up with the rainfall expected along this front.

Excessive Rainfall Outlook

The Weather Prediction Center has issued a level 3, moderate, excessive rainfall outlook. This outlook only reaches a level 4.
