Debby will slowly move inland to the north northeast across the Suwannee River Valley of inland Northeast Florida through the day Monday. Widespread flooding rainfall will overspread northeast Florida and southeast Georgia Monday and Monday night. As Debby drifts across coastal Southeast Georgia Tuesday, it may begin to stall into Tuesday Night, continuing a widespread flooding rainfall event. Excessive storm total rainfall of 8 to 16 inches is expected. Locally higher amounts near 20 inches are possible across southeast Georgia. This amount of rainfall will create an extreme threat of flash flooding through Tuesday and moderate to major river flooding on many area rivers. Outer rainbands with heavy rainfall, strong wind gusts and isolated tornadoes will continue to move across northeast Florida and southeast Georgia through Monday. Tropical storm warnings have been posted for most counties across southeast Georgia and northeast Florida, with hurricane warnings for portions of the Suwannee River Valley. The strongest winds and gusts are expected Monday through early Tuesday morning. The higher gusts will occur in squalls of heavy rainfall, over lakes, rivers, open pastures and along the coast. Storm surge inundation of 2 to 4 feet is expected along the southeast Georgia coast, with up to 3 feet of storm surge along the northeast Florida coast. Heavy coastal rainfall combined with surge will create significant flooding issues, especially in poor drainage areas of coastal communities. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Protect against life-threatening rainfall flooding having possible devastating impacts across southeast Georgia and northeast Florida. Potential impacts include: - Extreme rainfall flooding may prompt numerous evacuations and rescues. - Rivers and tributaries may overwhelmingly overflow their banks in many places with deep moving water. Small streams, creeks, canals, and ditches may become raging rivers. Flood control systems and barriers may become stressed. - Flood waters can enter numerous structures within multiple communities, some structures becoming uninhabitable or washed away. Numerous places where flood waters may cover escape routes. Streets and parking lots become rivers of raging water with underpasses submerged. Driving conditions become very dangerous. Numerous road and bridge closures with some weakened or washed out. Protect against life-threatening rainfall flooding having possible significant to extensive impacts across southeast Georgia, including the Golden Isles, and the Suwannee River Valley and near the I-10 corridor of northeast Florida. * WIND: Protect against life-threatening wind having possible extensive impacts across southeast Georgia and northeast Florida. Potential impacts in this area include: - Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks. - Many large trees snapped or uprooted along with fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges, causeways, and access routes impassable. - Large areas with power and communications outages. Also, protect against dangerous wind having possible limited to significant impacts across the Suwannee River Valley. * SURGE: Protect against life-threatening surge having possible significant impacts across coastal southeast Georgia. Potential impacts in this area include: - 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 erosion with heavy surf breaching dunes. Strong and numerous rip currents. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. Elsewhere across Northeast Florida and Southeast Georgia, little to no impact is anticipated. * TORNADOES: Protect against a dangerous tornado event having possible significant impacts across southeast Georgia and northeast Florida. Potential impacts include: - The occurrence of scattered tornadoes can hinder the execution of emergency plans during tropical events. - 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 homes demolished, boxcars overturned, large trees snapped or uprooted, vehicles tumbled, and small boats tossed about. Dangerous projectiles can add to the toll. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: All preparations to protect life and property in accordance with your emergency plan should be complete. Failure to adequately shelter may result in serious injury or loss of life. Always heed the advice of local officials and comply with any orders that are issued. Remember, during the storm 9 1 1 Emergency Services may not be able to immediately respond if conditions are unsafe. This should be a big factor in your decision making. Rapidly rising flood waters are deadly. If you are in a flood-prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, turn around don't drown! If a Tornado Warning is issued for your area, be ready to shelter quickly, preferably away from windows and in an interior room not prone to flooding. If driving, scan the roadside for quick shelter options. If in a place that is vulnerable to high wind, such as near large trees, a manufactured home, upper floors of a high-rise building, or on a boat, consider moving to a safer shelter before the onset of strong winds or flooding. Closely monitor weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- The next local statement will be issued by the National Weather Service in Jacksonville FL around 6 AM EDT, or sooner if conditions warrant. $$
