Efforts should now be underway to secure all properties. - Dangerous wind is possible. Failure to adequately shelter may result in injury. - 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: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 2-4 feet above ground somewhere within surge prone areas - Window of concern: Begins early Tuesday afternoon - CURRENT THREAT TO LIFE AND PROPERTY: Moderate - The storm surge threat has remained nearly steady from the previous assessment. - Emergency plans should include a reasonable threat for dangerous storm surge flooding of greater than 3 feet above ground. - To be safe, earnestly prepare for the potential of significant storm surge flooding impacts. Evacuation efforts should now be brought to completion. Evacuations must be complete before driving conditions become unsafe. - Life-threatening inundation is possible. Failure to heed evacuation orders may result in serious injury or loss of life. Leave if evacuation orders are given for your area. Consider voluntary evacuation if recommended. Poor decisions may 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 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. * FLOODING RAIN - LATEST LOCAL FORECAST: - Peak Rainfall Amounts: 4-8 inches, with locally higher amounts - CURRENT THREAT TO LIFE AND PROPERTY: Elevated - The flooding rain threat has remained nearly steady from the previous assessment. - Emergency planning should include a reasonable threat for minor flooding where peak rainfall totals are near amounts conducive for localized flash flooding and rapid inundation. - To be safe, prepare for the potential of limited flooding rain impacts. - Localized flooding is possible. If flood related watches and warnings are issued, heed recommended actions. - POTENTIAL IMPACTS: Limited - Localized rainfall flooding may prompt a few evacuations. - Rivers and tributaries may quickly rise with swifter currents. Small streams, creeks, canals, arroyos, and ditches may become swollen and overflow in spots. - 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. * TORNADO - LATEST LOCAL FORECAST: - Situation is unfavorable for tornadoes - CURRENT THREAT TO LIFE AND PROPERTY: None - The tornado threat has remained nearly steady from the previous assessment. - Emergency planning need not include a threat for tornadoes. Showers and thunderstorms with strong gusty winds may still occur. - Little to no preparations needed to guard against tropical tornadoes. - Ensure readiness for the next tropical tornado event. - POTENTIAL IMPACTS: Little to None - Little to no potential impacts from tornadoes.
