Weather: Birmingham

Hurricane Isaias made landfall earlier this evening near Destin, FL with max sustained winds of 105 MPH and a central pressure of 971 mb. The system will gradually weaken as it continues to move north across the state. As it weakens, the wind field will expand, overspreading most of Central Alabama. Winds will gust as high as 50 to 60+ mph late tonight 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 far southeast portions of Central Alabama.

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.
