A familiar problem for our friends along the lakeshore will unfortunately become more pronounced over the next few days. A Lakeshore Flood Warning is in effect for Wayne, Monroe, Macomb, St. Clair and Sanilac counties until Tuesday and could possibly be extended even longer depending on the track of a "cut-off" area of low pressure .

The problem aside from the rain it's producing, will be the consistent EASTERLY winds pilling up the water along the shores of the lakes. Since this storm is slow moving it'll take nearly two days for it to change our wind direction, which would allow the warning to expire.

A Cut-off Low?

This type of low pressure system is very slow moving and can create miserable weather for several days. They are also capable of creating severe weather and flooding issues, which we also have a slight risk of. These lows usually occur when they disconnect from the jet stream, or upper level wind flow. This causes them to wobble and even retrograde around until the jet stream's longwave pattern picks them up or they deteriorate. This is what's contributing to our unchanging weather and persistent easterly winds.
