A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, somewhere within this area within the next 36 hours A Tropical Storm Warning means tropical storm-force winds are expected somewhere within this area within the next 36 hours * LOCATIONS AFFECTED - Kiln - Pearlington - Bay St. Louis - Diamondhead - Waveland * WIND - LATEST LOCAL FORECAST: Tropical storm force winds remain possible - Peak Wind Forecast: 20-30 mph with gusts to 40 mph - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 39 to 57 mph - The wind threat has remained nearly steady from the previous assessment. - PLAN: Plan for hazardous wind of equivalent tropical storm force. - PREPARE: Efforts to protect property should now be underway. Prepare for limited wind damage. - ACT: Act now to complete preparations before the wind becomes hazardous. - POTENTIAL IMPACTS: Limited - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. 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. * STORM SURGE - LATEST LOCAL FORECAST: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 3-5 feet above ground somewhere within surge prone areas - Window of concern: Friday morning until Saturday morning - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm surge flooding greater than 3 feet above ground - The storm surge threat has remained nearly steady from the previous assessment. - PLAN: Plan for life-threatening storm surge flooding of greater than 3 feet above ground. - PREPARE: Evacuation efforts and flood preparations should soon be brought to completion before conditions become unsafe. - ACT: Leave immediately if evacuation orders are given for your area to avoid being cut off from emergency services or needlessly risk lives. - POTENTIAL IMPACTS: Significant - Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major beach and shoreline erosion. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. * FLOODING RAIN - LATEST LOCAL FORECAST: - Peak Rainfall Amounts: 1-3 inches, with locally higher amounts - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Little or no potential for flooding rain - The flooding rain threat has remained nearly steady from the previous assessment. - PLAN: There is little or no potential for flooding rain. - PREPARE: Little to no preparations are needed to protect against flooding rain at this time. - ACT: Monitor for changes to the forecast. - POTENTIAL IMPACTS: Little to None - Little to no potential impacts from flooding rain. * TORNADO - LATEST LOCAL FORECAST: - Situation is unfavorable for tornadoes - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Tornadoes not expected - 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.
