...TROPICAL STORM WARNING IN EFFECT...
Hurricane Isaias continues to move north towards the central Gulf Coast this afternoon. It is expected to make landfall as a hurricane along the coast of the western Florida Panhandle this evening. Isaias will gradually weaken as it moves north across Alabama overnight into Saturday. Tropical storm force wind gusts are expected across portions of East and Northeast Mississippi, as early as this evening in southeastern Mississippi, and overnight into Saturday across eastern and northeastern Mississippi. Downed trees and power outages are possible in these areas. Heavy rainfall and flash flooding are also possible, with greatest impacts expected generally across southeast to east Mississippi. Conditions are forecast to gradually improve late Saturday afternoon into Saturday evening.
Peak Wind Forecast: 15-25 mph with gusts to 35 mph
The wind threat has remained nearly steady from the previous assessment. PLAN: The sustained wind should remain less than tropical storm force. Conditions may still be gusty. PREPARE: Listen for any instructions from local officials. ACT: Ensure emergency readiness should the forecast change.
Little to no additional wind impacts expected. Community officials are now assessing the extent of actual wind impacts accordingly.
Peak Rainfall Amounts: 1-3 inches, with locally higher amounts
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. Evacuations and rescues are possible. PREPARE: Consider protective actions if you are in an area vulnerable to flooding. ACT: Heed any flood watches and warnings. Failure to take action may result in serious injury or loss of life.
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, canals, 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.
Situation is unfavorable for tornadoes
The tornado threat has remained nearly steady from the previous assessment. PLAN: Tornadoes are not expected. Showers and thunderstorms with gusty winds may still occur. PREPARE: Little to no preparations needed to protect against tornadoes at this time. Keep informed of the latest tornado situation. ACT: Listen for changes in the forecast.
Little to no potential impacts from tornadoes.
