Gulf Coast braces for impact as Alberto approaches
ST. PETERSBURG, FLA. — Beaches in Florida were largely empty ahead of Memorial Day as the first named storm of the Atlantic hurricane season, subtropical storm Alberto, approached the northern Gulf Coast carrying brisk winds and heavy rain.
The storm disrupted long holiday weekend plans from Pensacola in the Florida Panhandle to Miami Beach on Florida’s southeastern edge. Lifeguards posted red flags along the white sands of Pensacola Beach, where swimming and wading were banned amid high surf and dangerous conditions.
It also triggered mandatory evacuations of some small, sparsely populated Gulf Coast barrier islands in one Florida county. The Florida Division of Emergency Management said in a statement Sunday that a mandatory evacuation has been issued in Franklin County for all barrier islands there and those in the county living directly on the coast in mobile homes or in recreation vehicle parks.
Alberto got an early jump on the 2018 hurricane season, which doesn’t officially start until June 1. The storm prompted Florida, Alabama and Mississippi to launch emergency preparations over the weekend amid expectations Alberto would reach land sometime Monday. Rough conditions were expected to roil the seas off the eastern and northern Gulf Coast region through Tuesday.
“These swells are likely to cause life-threatening surf and rip current conditions,” the National Hurricane Center in Miami said in a statement.
Gusty showers were to begin lashing parts of Florida on Sunday, and authorities were warning of the possibility of flash flooding.
At 5 p.m. Sunday, Alberto was centred about 265 kilometres west of Tampa and had maximum sustained winds of 58 km/h. Forecasters said Alberto has most recently taken a northnorthwest track that would bring it over the northern Gulf of Mexico during the night and make landfall on or in the vicinity of the Florida Panhandle on Monday.
A subtropical storm like Alberto has a less defined and cooler centre than a tropical storm, and its strongest winds are found farther from its centre. Subtropical storms can develop into tropical storms, which in turn can strengthen into hurricanes. Forecasters cautioned that heavy rain and tropical storm conditions could reach the northern Gulf Coast well ahead of the centre of Alberto making landfall.
Meanwhile, the National Hurricane Center in Miami discontinued all storm surge warnings for most of the state’s peninsula.
Mark Bowen, the Bay County Emergency management director, said at a Sunday afternoon news conference that the concern isn’t with storm surge due to the timing of landfall and the tides. He said Alberto’s biggest threat will be its heavy rains, with forecasts of anywhere from 100 to 300 millimetres of rain in some areas.
In Taylor County, there were voluntary evacuations for those in coastal zones and beach communities, mobile homes, RV parks and low-lying areas. In Miami, organizers called off the sea portion of the Miami Beach Air and Sea Show on Sunday because of heavy rain and rough waters. And in the Tampa Bay area on the central Gulf Coast, cities offered sandbags for homeowners worried about floods.
The hurricane centre said Sunday that a tropical storm warning was in effect from Bonita Beach, Fla., to the MississippiAlabama border.
