Our Forecast
Alberto is moving inland. It is barely a subtropical storm. It should be downgraded to a depression soon. By late tomorrow morning, we expect that Alberto will be a remnant area of low pressure.
The remnant low is expected to track mainly to the north-northwest. It is expected to bring heavy rains along its path. Some of the heaviest rains currently near and to the northwest of the center. Peak rain rates near the center are generally between .5 and 1 inch per hour. There is also a band of heavy storms well northeast of the center over northern Georgia. Higher rain rates are likely occurring there. These rains in the outer bands should decrease in intensity during the overnight hours, while there may be an enhancement of the rains near the center.
Expected Impacts Onshore
Southeastern United States: Flash flooding could lead to travel delays, especially in southern Alabama near where the center of Alberto tracks. There, significant travel delays are possible.
Our next advisory will be issued by 3 AM CDT

The yellow cone represents track error from the previous five hurricane seasons. Over the past five hurricane seasons, the center of the storm tracked within the yellow cone 75% of the time. The cone does not represent the forecast uncertainty in the current advisory for this storm. In addition, hurricane-force winds, very high tides, large waves, and heavy rainfall can often extend well outside the yellow cone.
