Hurricane Sally threatens historic floods

Hurricane Sally strengthened to a Category 2 system with 100 mile-an-hour winds and heavy rain as it bore down on the US Gulf Coast early on Wednesday.

Forecasters warned of “historical flooding” as the storm inched north-northwest towards the coast at around two miles per hour, with the National Hurricane Centre’s forecast map showing its centre as likely to make landfall on Wednesday morning in Alabama, near the Florida border.

Rain fell sideways and began covering roads in Pensacola, Florida, and Mobile, with more than 80,000 power customers in the area without electricity, according to poweroutage.us.

“A hurricane moving at two miles per hour is stalled for all intents and purposes,” said Brian McNoldy, a hurricane researcher at the University of Miami.

“If they aren’t moving along and they just kind of sit there, you’re going to get a ridiculous amount of rain.”

By Tuesday night, hurricane warnings stretched from coastal Mississippi to the Florida Panhandle. There also was a threat the storm could spawn tornadoes and dump isolated rain accumulations of 30 inches in spots from the Florida Panhandle to southeast Mississippi.

Heavy rain and surf pounded the barrier island of Navarre Beach, Florida, on Tuesday and road signs wobbled in the wind.

“This is going to be historic flooding along with the historic rainfall,” Stewart said. “If people live near rivers, small streams and creeks, they need to evacuate and go somewhere else.”

Forecasters warned Sally could unleash flooding similar to that caused by Hurricane Harvey in 2017 in swamping the Houston metropolitan area.

Mississippi governor Tate Reeves urged people in the southern part of the state to prepare for the potential for flash flooding. He said about 120 people were in shelters in Mississippi.

Meanwhile, Tropical Storm Teddy has now become a hurricane with maximum sustained winds of 100 mph, the National Hurricane Center said.

Teddy is located about 820 miles east of the Lesser Antilles and hurricane-force winds extend outward up to 25 miles from the centre, with tropical-storm-force winds extending outward up to 175 miles.

Some strengthening is forecast during the next few days and Teddy is likely to become a major hurricane and could reach Category 4 strength.
