Hurricane Sandy began to affect the Palm Beach County coast and its adjacent Atlantic waters with tropical storm force winds during the evening of October 25th as it moved slowly north across the northwest Bahamas. Tropical storm force wind gusts were first observed along the coastal Palm Beach County region by early in the evening of October 25th. Several WeatherFlow sensors along and near the Palm Beach County coast recorded Tropical Storm force wind gusts during the evening of October 25th with a peak wind gust of 67 mph observed at Jupiter. However, as Hurricane Sandy continued to move slowly north and then northeast over the Atlantic waters north of the Bahamas through the 28th the main impact along the Palm Beach County coast were large northeast swells generated by the storm which pummeled the Southeast Florida coast with significant beach erosion and coastal flooding. Large breaking waves of possibly over 20 feet were estimated along the coast. As a result, major coastal flooding occurred with the most significant impacts experienced from central Palm Beach north, including the Manalapan area where beachfront structures were threatened by water intrusion. In all, there was an estimated $14 million in damage sustained in Palm Beach County. A total of 44,270 customers lost power.
A maximum storm tide of 5.2 feet above mean lower low water (MLLW) was observed at Lake Worth Pier on October 28th at 712 AM EDT along with a maximum storm surge of 2.28 feet on October 28th at 236 AM EDT.

A maximum storm tide of 4.15 feet above mean lower low water (MLLW) was observed at Virginia Key on October 28th at 848 AM EDT, along with a maximum storm surge of 1.44 feet. Similar tide and surge levels were measured at the highest daily high tide during this period, generally between 7 and 9 AM. Large breakers in excess of 10 feet combined with the high tide levels led to major beach erosion and coastal flooding, particularly in the area along A1A in Fort Lauderdale Beach between Las Olas Boulevard and NE 20 St. Water reached up to 2 blocks inland and sand up to 2 feet deep accumulated along A1A. That portion of the roadway was closed for several days, leading to significant damage. No damage estimate is available at this time.

Hurricane Sandy began to affect the Broward County coast and its adjacent Atlantic waters with tropical storm force winds during the afternoon of October 25th as it moved slowly north across the northwest Bahamas. Tropical storm force wind gusts were first observed along the coastal Broward County region by late on the afternoon of October 25th continuing into the evening. Several WeatherFlow sensors along and near the Broward County coast recorded Tropical Storm force wind gusts during the evening of October 25th with a peak wind gust of 63 mph observed at Port Everglades and 59 mph at Pompano Beach. However, as Hurricane Sandy continued to move slowly north and then northeast over the Atlantic waters north of the Bahamas through the 28th the main impact along the Broward County coast were large northeast swells generated by the storm which pummeled the Southeast Florida coast with severe beach erosion and coastal flooding. Large breaking waves of over 10 feet were estimated along the Broward County coast. As a result, major coastal flooding occurred along A1A in Fort Lauderdale Beach, mainly between Las Olas Boulevard and NE 20th Street. This resulted in this stretch of road being closed the entire weekend, along with a few others, as well as some neighborhoods being cut off. A few homes also sustained water damage. The large waves brought sea water and sand a couple of feet deep onto A1A with the inland extent being about 2 city blocks in some locales.
Nearest tide gauge at Virginia Key reported a maximum storm tide of 4.15 feet above mean lower low water (MLLW) on October 28th at 848 AM, along with a maximum storm surge of 1.44 feet.
