Weather: Birmingham

Hurricane Isaias will continue to move towards the Northern Gulf Coast, making landfall Friday evening. Winds will gust as high as 50 to 60+ mph late Friday night through Saturday, resulting in the potential for widespread downed trees and power lines. Rainfall amounts of 1.5 to 4 inches with locally higher amounts up to 5 inches will result in the potential for flash flooding, especially in urban and other poor drainage areas. Isolated tornadoes may develop across portions of Central Alabama, mainly east of Interstate 65. Eastern portions of the state are in a level 2 of 5 severe risk to account for this activity.
