...TROPICAL STORM WATCH REMAINS IN EFFECT...
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.

WIND: POTENTIAL IMPACTS
Damage to porches, awnings, carports, sheds, and unanchored mobile and manufactured homes. Unsecured lightweight objects blown about. Many large tree limbs broken off. A few trees snapped or uprooted, especially weaker trees. Some fences and roadway signs blown over. A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. Scattered power and communications outages.
FLOODING RAIN: LATEST LOCAL FORECAST
Peak Rainfall Amounts: 1-3 inches, with locally higher amounts
FLOODING RAIN: THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY
The flooding rain threat has remained nearly steady from the previous assessment. PLAN: Emergency plans should include the potential for moderate flooding from heavy rain.

Failure to take action may result in serious injury or loss of life.
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.

PREPARE: Those living in manufactured homes or on boats are urged to relocate to safe shelter before hazardous weather arrives. ACT: Listen for tornado watches and warnings. If a tornado warning is issued, be ready to shelter quickly.
TORNADO: POTENTIAL IMPACTS
Several places may experience tornado damage with a few spots of considerable damage, power loss, and communications failures. Locations could realize roofs torn off frame houses, mobile and manufactured homes demolished, large trees snapped or uprooted, and vehicles tumbled. Dangerous projectiles can add to the toll.
