Weather: Birmingham

Hurricane Isaias will continue to move towards the Northern Gulf Coast, making landfall Friday evening. Winds will gust as high as 40 to 50 mph Friday night through Saturday, with isolated wind gusts as high as 60 mph, resulting in the potential for numerous downed trees and power lines. Rainfall amounts of 2 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. A threat for isolated tornadoes may develop across portions of Central Alabama along and east of the track on Saturday, with the highest potential along and east of Interstate 65. Confidence is low to medium at this time.

FLOODING RAIN: POTENTIAL IMPACTS

Moderate rainfall flooding may prompt several evacuations and rescues. Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, and ditches overflow. Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures.
