Southeast US under major storm warning as hurricane watch issued for parts of Cuba and Mexico

SAN JUAN, Puerto Rico (AP) — Hurricane watches were issued for parts of Cuba and Mexico on Monday as a cluster of storms located south of the Cayman Islands is expected to strengthen into a major hurricane in upcoming days with it moving north toward the US, weather forecasters said.

The disturbance is expected to become Hurricane Helene on Wednesday as it approaches the Gulf Coast, according to the National Hurricane Center.

"It could be a major hurricane when it reaches the northeastern Gulf Coast on Thursday," the center said.
Michael Lowry, a hurricane specialist and storm surge expert, wrote in his latest update that it's likely a Category 3 or stronger hurricane "will threaten parts of north Florida or its sweeping Big Bend before the work week is done."

The cluster of storms was located about 130 miles (205 kilometres) south-southwest of Grand Cayman on Monday. It had maximum sustained winds of 30 mph (45 kph) and was moving north at 6 mph (9 kph).

A hurricane watch was in effect for the Cuban province of Pinar del Rio and eastern Mexico from Cabo Catoche to Tulum. A tropical storm warning was in effect for eastern Mexico from Río Lagartos to Tulum and for the Cuban provinces of Artemisa, Pinar del Río and the Isle of Youth.

Up to eight inches of rain is forecast for western Cuba and the Cayman Islands with isolated total of some 12 inches (30 centimetres). Up to four inches (10 centimetres) of rain is expected for the eastern Yucatán Peninsula, with isolated total of more than 6 inches (15 centimetres) inches.

Heavy rainfall also is forecast for the Southeast US starting on Wednesday, threatening flash and river flooding, according to the National Hurricane Center.

Meanwhile, up to four feet (1.2 meters) of storm surge is forecast for parts of Cuba and Mexico.

On Monday, authorities in the Cayman Islands closed schools as forecasters warned of heavy flooding associated with the disturbance, expected to cut a path between Cuba and Mexico's Yucatán peninsula in upcoming days.

Helene would be the eighth named storm of the Atlantic hurricane season which runs from June 1 to November 30.

The National Oceanic and Atmospheric Administration has predicted an above-average Atlantic hurricane season this year because of record-warm ocean temperatures. It forecast 17 to 25 named storms, with four to seven major hurricanes of Category 3 or higher.
