PLAN: Plan for dangerous wind of equivalent strong tropical storm force. PREPARE: Remaining efforts to protect life and property should be completed as soon as possible. Prepare for significant wind damage. ACT: Move to safe shelter before the wind becomes hazardous. POTENTIAL IMPACTS: Significant Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over. Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable. Scattered power and communications outages, but more prevalent in areas with above ground lines. * STORM SURGE LATEST LOCAL FORECAST: Localized storm surge possible Peak Storm Surge Inundation: The potential for 1-3 feet above ground somewhere within surge prone areas Window of concern: Monday afternoon until Tuesday afternoon THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm surge flooding greater than 1 foot above ground The storm surge threat has remained nearly steady from the previous assessment. PLAN: Plan for storm surge flooding greater than 1 foot above ground. PREPARE: Complete preparations for storm surge flooding, especially in low-lying vulnerable areas, before conditions become unsafe. ACT: Leave immediately if evacuation orders are given for your area. POTENTIAL IMPACTS: Limited Localized inundation with storm surge flooding mainly along immediate shorelines and in low-lying spots, or in areas farther inland near where higher surge waters move ashore. Sections of near-shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road. Moderate beach erosion. Heavy surf also breaching dunes, mainly in usually vulnerable locations. Strong rip currents. Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. * FLOODING RAIN LATEST LOCAL FORECAST: Flood Watch is in effect Peak Rainfall Amounts: Additional 4-8 inches, with locally higher amounts THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for major flooding rain The flooding rain threat has remained nearly steady from the previous assessment. PLAN: Emergency plans should include the potential for major flooding from heavy rain. Evacuations and rescues are likely. PREPARE: Strongly consider protective actions, especially if you are in an area vulnerable to flooding. ACT: Heed any flood watches and warnings. Failure to take action will likely result in serious injury or loss of life. POTENTIAL IMPACTS: Extensive Major rainfall flooding may prompt many evacuations and rescues. Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, canals, arroyos, and ditches may become dangerous rivers. In mountain areas, destructive runoff may run quickly down valleys while increasing susceptibility to rockslides and mudslides. Flood control systems and barriers may become stressed. Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out. * TORNADO LATEST LOCAL FORECAST: Situation is favorable for tornadoes THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for several tornadoes The tornado threat has remained nearly steady from the previous assessment. PLAN: Emergency plans should include the potential for several tornadoes with a few possibly intense having larger damage paths. PREPARE: Those living in manufactured homes or on boats are urged to relocate to safe shelter before hazardous weather arrives. ACT: Listen for tornado watches and warnings. If a tornado warning is issued, be ready to shelter quickly. POTENTIAL IMPACTS: Significant 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. * FOR MORE INFORMATION: https://www.weather.gov/hfo
