From the NHC 5:25 PM Local Advisory for S. Florida / Miami
WIND:
Prepare for life-threatening wind having possible devastating impacts
across South Florida. Potential impacts include:
* 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.
SURGE:
Prepare for life-threatening surge having possible devastating impacts
across coastal Collier, Mainland Monroe, coastal Miami-Dade counties
including Biscayne Bay. Potential impacts in this area include:
* 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.
* Also, prepare for life-threatening surge having possible significant to extensive impacts across immediate coastal Broward and Palm Beach
counties.
FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant impacts across the east coast metro of South Florida. Potential impacts include:
* Moderate rainfall flooding may prompt several evacuations and rescues.
* Ditches and canals may quickly become swollen with swift currents and overspill their banks in a few places, especially in usually vulnerable spots.
* 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.
* Prepare for locally hazardous rainfall flooding having possible limited impacts across the rest of South Florida.
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.
