Tropical Storm and Storm Surge in Florida, August 26 to 31, 2012

The center of Tropical Storm Isaac moved over the Florida Straits south of the Florida Keys on Sunday, August 26th, passing just south of Key West. Rain bands and winds on the north side of the circulation of Isaac affected Southeast Florida throughout the day of the 26th and part of the 27th. Highest winds over land were recorded along and near the southeast Florida coast where the highest sustained winds ranged from 40-45 mph, with 25-35 mph sustained winds over most inland areas as well as over southwest Florida. Highest wind gusts ranged from 50-60 mph over most land areas to as high as 65 mph along the Atlantic coast and just offshore.

Three-day rainfall totals ending at 8 AM August 28th ranged from 5-7 inches across southeast Florida to 3-5 inches over interior and southwest Florida. The primary exception was over northern metro Broward County and much of Palm Beach County where 8 to 12 inches fell, with maximum amounts up to 15-18 inches from west of Boynton Beach to Wellington, The Acreage, Royal Palm Beach and Loxahatchee. These areas of highest rainfall amounts experienced severe flooding with communities cut off for several days after the storm.

Maximum storm tide values were observed at 4.9 feet at Naples, with estimates of 5 to 7 feet along the southern Collier County coast from Goodland to Everglades City. Highest estimated inundation values of up to 3 feet above ground level were noted in Goodland and Everglades City. Major beach erosion was also observed along the Collier County beaches, with moderate beach erosion along the Atlantic beaches.

All of the associated effects of Isaac in south Florida resulted in about $17.2 million in property damage. Specifically, Isaac's inland flood waters resulted in about $10 million in damages, mostly in Palm Beach and Broward counties. Flooding caused by storm tides along the coast in Collier County resulted in about $400 thousand in damage. Damage from beach erosion in Collier and Broward counties was estimated at $6 million. Wind damage was estimated at $750,000.

Approximately 113,000 customers lost power during the storm in South Florida.

Moderate to locally severe beach erosion was noted along the Broward County coast with estimated surge heights of 1 to 1.5 feet based on the tide gauge at Virginia Key south of downtown Miami. Hardest hit areas were the Hollywood and Hillsboro beaches where beach erosion was severe.

Maximum storm surge at Virginia Key was measured at 1.3 feet, leading to moderate to locally severe beach erosion along the Miami-Dade County coast.

Moderate to severe flooding occurred over parts of northern metro Broward County. Hardest hit areas were in Lauderhill from Commercial Boulevard to NW 44 ST between University Drive and Pine Island Road where canals overflowed their banks and streets were flooded for a few days. A few homes sustained minor water damage. A few on-ramps to the Sawgrass Expressway were closed due to standing water.

Rainfall amounts in these areas were in the 8-12 inch range.

Moderate to severe flooding affected a large portion of metro Palm Beach County west of the Florida Turnpike. Hardest hit communities include The Acreage, Royal Palm Beach, Loxahatchee and Wellington. Canals were overtopped and communities were stranded by high water for several days after the rains stopped. Few homes suffered water damage, but major damage was sustained to infrastructure, including roads and water management structures.

Rainfall amounts as high as 16 inches were measured in Royal Palm Beach and Loxahatchee, with estimates in excess of 18 inches in a two-day period.

Severe beach erosion and coastal flooding occurred on Monday, August 27th as the center of Tropical Storm Isaac moved into the Gulf of Mexico. A storm surge of 2.05 feet was measured at the Naples pier. Farther east along the coast, inundation depths as high as 3 feet were reported in Goodland and Everglades City. Inundation in the Naples area was about 1 foot. Most damage from coastal flooding was to infrastructure in the Goodland and Everglades City areas and was estimated at $400,000.

Severe beach erosion in the Naples and Marco Island areas led to damage estimated at $5.6 million.

Flooding persisted over the western communities of Palm Beach County through the end of August as a result of torrential rains from Tropical Storm Isaac which fell on August 26th and 27th.

Damage estimates and impacts caused by the flooding is included in the Flash Flood entry for Palm Beach County.
