Alberto made landfall in Laguna Beach, Florida Monday afternoon around 5 PM ET and had since weakened to a subtropical depression. The current track from the National Hurricane Center takes the storm to the north through Alabama and into the Ohio Valley later this week.


Although Alberto has significantly weakened, it is still packing a punch as far as heavy rain and flash flooding across Central Alabama. Lighter rain bands on the east side of the system will continue to filter into the Valley this afternoon, thanks to a robust moisture feed from the Gulf of Mexico. Some of these storms that fire up could produce brief periods of localized heavy rainfall. We could pick up an additional 1-2" in spots through Wednesday, as rain chances still remain high tomorrow with remnant moisture from Alberto. A Flash Flood Watch remains in effect through Wednesday morning; even a little bit of additional rain can cause issues on top of the rain we already saw last week. For the remainder of the afternoon, gusty winds will transition to more breezy conditions. Rain chances remain high for Wednesday, but some more sunshine will break through the clouds by Thursday!

TIMING:  Highest impacts tonight through the lunch hour Tuesday, while higher than average rain chances will continue through Wednesday and Thursday.

IMPACTS:  We still expect heavy rain at times tonight in the bands of rain that will be wrapping around the center of Alberto.  We may see an additional 1-3" of rain across the Valley between now and Tuesday afternoon, and this could lead to a flash flooding risk.  As the center of circulation passes by the area, winds may gust to 25-35 mph.  That may cause some trees to fall down since the soil is already very wet.  It would not be as widespread of an issue as we had with Irma, but still something we will be watching.

HOW TO PREPARE:  Download the FREE WTVM weather app to keep track of any watches and warnings that may come out overnight or early Tuesday.  Make sure you have something that can wake you up in the middle of the night if there is a watch or warning like our app or a weather radio!  Otherwise, most will just enjoy a windy and wet night with no major problems.  We will be monitoring things closely through the overnight hours!
