Tropical Storm Helene is gaining strength as it moves toward the Gulf of Mexico, where it's expected to rapidly intensify before reaching Florida as a major hurricane.

Helene is expected to strengthen into a Category 3 storm before making landfall Thursday night in the Big Bend region, but FOX 13 meteorologist Dave Osterberg warned it could be even stronger.

As of 8 a.m. Wednesday, Helene was located at 21.1 N and 86.2 W, had maximum sustained winds of 70 miles an hour and was moving northwest at 9 miles an hour.

The National Hurricane Center said the storm will grow wider, leading to far-reaching impacts across the Bay Area and all of Central Florida, despite being outside the NHC's forecast cone.

Osterberg said record high water temperatures will provide "unlimited fuel" for rapid intensification.

Storm watches and warnings

A hurricane warning is in effect from Anclote River to Mexico Beach. That includes coastal areas of Citrus, Hernando and Pasco counties.

A tropical storm warning has been issued for the rest of the state except the western Panhandle.

A storm surge warning has been issued from Flamingo to Indian Pass, including Tampa Bay and Charlotte Harbor.

A flood watch is in effect until Friday morning across the Bay Area and much of the state except east Central Florida and the western Panhandle.

What is the timeline for impacts in the Bay Area?

Rainy and windy conditions are expected to arrive in the region early Thursday, with the strongest impacts being felt Thursday afternoon, according to Osterberg.

Osterberg said any shift in the track, even just a few miles, will significantly change how Helene will impact the Bay Area.

"There's not a lot of room for error. There really isn't for a storm like this and the large size that it is," Osterberg said.

How strong are the potential impacts from Helene?

FOX 13 meteorologists say life-threatening storm surge is expected to be a major issue, with the potential to reach 15 feet along the coast from Citrus County northward into the Big Bend.

Wind gusts could top 70 miles an hour along the coast on Thursday afternoon, with tropical storm force winds extending as far as 250 miles from the center of the storm.

Significant rainfall is also expected, ranging from 5 to 10 inches on the coast to 2 to 4 inches inland.
