Tropical Cyclone Statement issued September 25 at 5:17PM EDT by NWS Melbourne FL HLSMLB This product covers East Central Florida **OUTER RAINBANDS ARRIVING FROM HELENE** **PREPARATIONS SHOULD BE RUSHED TO COMPLETION PRIOR TO SUNSET** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - None * CURRENT WATCHES AND WARNINGS: - A Tropical Storm Warning is in effect for Coastal Indian River, Coastal Martin, Coastal Saint Lucie, Coastal Volusia, Inland Indian River, Inland Martin, Inland Northern Brevard, Inland Saint Lucie, Inland Southern Brevard, Inland Volusia, Mainland Northern Brevard, Mainland Southern Brevard, Northern Brevard Barrier Islands, Northern Lake, Okeechobee, Orange, Osceola, Seminole, Southern Brevard Barrier Islands, and Southern Lake * STORM INFORMATION: - About 520 miles southwest of Leesburg FL - 22.5N 86.6W - Storm Intensity 85 mph - Movement North or 355 degrees at 12 mph SITUATION OVERVIEW ------------------ Hurricane Helene is located about 460 miles southwest of Tampa as of 5 PM, emerging shortly into the Gulf of Mexico. Helene is forecast to strengthen into a Major Hurricane while moving north and northeast across the Gulf of Mexico tonight and tomorrow. Landfall is forecast along the FL Big Bend to the eastern Panhandle Thursday evening as a strong Category 3 or Category 4 storm. Tropical storm force winds are likely to encompass a large area to the east of Helene's center, which includes the entire Florida Peninsula. Tropical Storm Warnings remain in effect for all of east central Florida, as well as the adjacent Atlantic waters. Frequent tropical storm force gusts will be possible across the area Thursday into Thursday evening. The potential for gusts up to 60-65 mph will exist, particularly northwest of I-4, along the Atlantic coast and in vicinity of Lake Okeechobee. In addition to strong wind gusts, a few to several tornadoes embedded in rain bands are possible beginning late tonight and lasting through Thursday afternoon. Outer rain bands have begun to impact the local area late this afternoon, and will increase in frequency over the next 24 hours as the system makes its closest approach to east central Florida early tomorrow afternoon. Locally higher rainfall totals will result from rain bands repeatedly moving over the same locations. Generally, 1 to 4 inches of total rainfall is forecast area-wide, with locally higher amounts of up to 6 inches possible through late Thursday. These rainfall amounts will be capable of producing flooding in low-lying and urban areas, especially in areas which have already received heavy rainfall this month. Along the coast, increasing, battering surf from late tonight through Thursday night will cause dangerous beach conditions. Run-up to the dune line and sea walls will result in beach erosion. Impacts will be greatest during the Thursday afternoon high tide, occurring between 3 PM and 5 PM. Marine conditions will become dangerous and small craft operators should remain in port. A High Surf Advisory wil be effective beginning at 10 PM tonight. Preparation efforts should be rushed to completion by sunset this evening. Do not let your guard down. This will be a very large storm and impacts will be experienced far from the center of the storm. Make sure your hurricane kit is fully stocked and safety plan in place. As conditions deteriorate tonight and tomorrow morning, be sure to have multiple ways to receive weather alerts that will wake you up. Any eastward shifts in the forecast track would increase the potential for additional impacts locally, so continue to monitor the latest forecasts from the National Hurricane Center and National Weather Service in Melbourne, Florida. POTENTIAL IMPACTS ----------------- * WIND: Protect against hazardous wind having possible limited impacts across East Central Florida. Potential impacts include: - 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. * FLOODING RAIN: Protect against dangerous rainfall flooding having possible significant impacts across east central Florida. Potential impacts include: - 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. * TORNADOES: Protect against a dangerous tornado event having possible significant impacts across most of east central 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. Protect against a tornado event having possible limited impacts across the Treasure Coast and vicinity of Lake Okeechobee. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials. * OTHER PREPAREDNESS INFORMATION: Now is the time to complete all preparations to protect life and property in accordance with your emergency plan. Ensure you are in a safe location before the onset of strong winds or possible flooding. If you are a visitor, be sure to know the name of the city or town in which you are staying and the name of the county or parish in which it resides. Listen for these locations in local news updates. Pay attention for instructions from local authorities. 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.
