...HURRICANE WARNING REMAINS IN EFFECT...
...STORM SURGE WARNING REMAINS IN EFFECT...

* WIND
- LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind
- Peak Wind Forecast: 35-45 mph with gusts to 60 mph
- Window for Tropical Storm force winds: early Friday afternoon until Monday morning

- CURRENT THREAT TO LIFE AND PROPERTY: Extreme
- The wind threat has remained nearly steady from the previous assessment.
- Emergency plans should include a reasonable threat for major hurricane force wind greater than 110 mph of equivalent Category 3 intensity or higher.
- To be safe, aggressively prepare for the potential of devastating to catastrophic wind impacts. Remaining efforts to secure properties should now be brought to completion.
- Extremely dangerous and life-threatening wind is possible. Failure to adequately shelter may result in serious injury, loss of life, or immense human suffering. Move to safe shelter before the wind becomes hazardous.

- POTENTIAL IMPACTS: Devastating to Catastrophic
- Structural damage to sturdy buildings, some with complete roof and wall failures. Complete destruction of mobile homes. Damage greatly accentuated by large airborne projectiles. Locations may be uninhabitable for weeks or months.
- Numerous large trees snapped or uprooted along with fences and roadway signs blown over.
- Many roads impassable from large debris, and more within urban or heavily wooded places. Many bridges, causeways, and access routes impassable.
- Widespread power and communications outages.

* STORM SURGE
- LATEST LOCAL FORECAST: Life-threatening storm surge possible
- Peak Storm Surge Inundation: The potential for 7-11 feet above ground somewhere within surge prone areas
- Window of concern: Begins Friday morning

- CURRENT THREAT TO LIFE AND PROPERTY: Extreme
- The storm surge threat has remained nearly steady from the previous assessment.
- Emergency plans should include a reasonable threat for extreme storm surge flooding greater than 9 feet above ground.
- To be safe, aggressively prepare for the potential of devastating to catastrophic 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, significant loss of life, or immense human suffering. Leave if evacuation orders are given for your area. Consider voluntary evacuation if recommended. Poor decisions may result in being cut off or needlessly risk lives.

- POTENTIAL IMPACTS: Devastating to Catastrophic
- Widespread deep inundation, with storm surge flooding greatly accentuated by powerful battering waves. Structural damage to buildings, with many washing away. Damage greatly compounded from considerable floating debris. Locations may be uninhabitable for an extended period.
- Near-shore escape routes and secondary roads washed out or severely flooded. Flood control systems and barriers may become stressed.
- Extreme beach erosion. New shoreline cuts possible.
- Massive damage to marinas, docks, boardwalks, and piers. Numerous small craft broken away from moorings with many lifted onshore and stranded.

* FLOODING RAIN
- LATEST LOCAL FORECAST: Flash Flood Watch is in effect
- Peak Rainfall Amounts: Additional 18-24 inches, with locally higher amounts

- CURRENT THREAT TO LIFE AND PROPERTY: Extreme
- The flooding rain threat has increased from the previous assessment.
- Emergency plans should include a reasonable threat of extreme flooding where peak rainfall totals vastly exceed amounts conducive for flash flooding and rapid inundation. Rescues and emergency evacuations are very likely.
- To be safe, aggressively prepare for the potential of devastating to catastrophic flooding rain impacts.
- Life-threatening flooding is possible. Failure to take action may result in serious injury, significant loss of life, or human suffering. If flood related watches and warnings are issued, heed recommended actions. Poor decisions may result in being cut off or needlessly risk lives. If vulnerable, relocate to safe shelter on higher ground before flood waters arrive.

- POTENTIAL IMPACTS: Devastating to Catastrophic
- 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.

* TORNADO
- LATEST LOCAL FORECAST:
- Situation is somewhat favorable for tornadoes

- CURRENT THREAT TO LIFE AND PROPERTY: Elevated
- The tornado threat has remained nearly steady from the previous assessment.
- When implementing emergency plans, include a reasonable threat for isolated tornadoes.
- To be safe, prepare for the potential of limited tornado impacts.
- Listen for tornado watches and warnings. Be ready to shelter quickly if a tornado approaches.

- POTENTIAL IMPACTS: Limited
- 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, chimneys toppled, 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.
