As of 11:00 am this morning, Sally strengthened to a Category 1 Hurricane. Sally is expected to make landfall Tuesday morning around Mobile, AL. Sally is going to be a very slow-moving hurricane — as currently, it is only moving at 6 mph. The primary hazards prior to landfall will be the torrential rainfall leading to a life-threatening flash flooding threat and storm surge. Winds as of the 1:00 PM update indicate 90 MPH winds.

Local Impacts

To account for the flooding potential, a Flash Flood Watch is in effect for areas south and west of I-59 towards Mobile. Rainfall amounts from anywhere of 6-10″ will be possible.

A Flash Flood Watch means that conditions may develop that lead to
Flash Flooding. Flash Flooding is a very dangerous situation. You
should monitor later forecasts and be prepared to take action should
Flash Flood Warnings be issued.

Further north, we’re still expecting a high flash flooding risk, but rapid weakening will occur once Sally makes landfall. For northern AL, rain rates will range from 2-6″ of rain.

As far as the severe weather threat goes, it will be very limited. The entire southeast will be overwhelmed with cloud cover keeping the air rather stable but moist. However with any tropical systems there will be the potential for quick spin-up tornadoes just about anywhere.
