Idalia is forecast to gain strength over the eastern Gulf as it moves closer to Florida. The following are the primary hazards of concern with Ten/Idalia: * Coastal Flooding/Surge - Higher than usual tides due to the combination of surge from Idalia and the full moon could lead to minor coastal flooding in vulnerable, low-lying coastal areas. * Rainfall - The majority of the rainfall associated with the system is forecast to fall from this afternoon through Wednesday. The greatest risk for flash flooding will be near the Gulf coast. Storm total rain amounts of 2-3 inches with localized higher amounts. The highest amounts are anticipated along the Gulf coast. * Wind - Increasingly gusty winds are forecast Tuesday through Thursday, particularly along the Gulf coast and adjacent coastal waters. * Tornadoes - A low-end tornado threat is possible through early Thursday as banding from the system moves ashore. POTENTIAL IMPACTS ----------------- * SURGE: Prepare for life-threatening surge having possible significant impacts across coastal Collier County. 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. Also, prepare for locally hazardous surge having possible limited impacts across coastal mainland Monroe county. * FLOODING RAIN: Prepare for locally hazardous rainfall flooding having possible limited impacts across South Florida. Potential impacts include: - Localized rainfall flooding may prompt a few evacuations. - Ditches and canals may quickly rise with swift currents. - Flood waters can enter a few structures, especially in usually vulnerable spots. A few places where rapid ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Several storm drains and retention ponds become near-full and begin to overflow. Some brief road and bridge closures. * WIND: Prepare for hazardous wind having possible limited impacts across areas of South Florida west of Lake Okeechobee. Potential impacts in this area include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Some 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. Elsewhere across South Florida, little to no impact is anticipated. * TORNADOES: Prepare for a tornado event having possible limited impacts across South Florida. Potential impacts include: - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings. Elsewhere across South Florida, little to no impact is anticipated. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Listen to local official for recommended preparedness actions, including possible evacuation. If ordered to evacuate, do so immediately. * OTHER PREPAREDNESS INFORMATION: Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. Always heed the advice of local officials and comply with orders that are issued. Do not needlessly jeopardize your life or the lives of others. * 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 Miami FL around 11 AM EDT, or sooner if conditions warrant. $$
