Hurricane Helene live updates: 1 dead in Florida as Category 4 storm makes landfall

Hurricane Helene's landfall may see "damaging winds" penetrate as far inland as major metro areas like Atlanta, Georgia, the National Hurricane Center warned.

The storm is "strengthening and expected to bring catastrophic winds and storm surge to the northeastern Gulf Coast," the NHC said in its latest update.

A hurricane warning is currently in place for parts of Florida and Georgia. This includes Tallahassee and Apalachicola, Florida, and Valdosta, Columbus and Macon, Georgia.

A tropical storm warning is in place for cities including Miami, Orlando, Jacksonville and Atlanta. Dothan, Alabama, Charleston, South Carolina, and Asheville, North Carolina are also under tropical storm warnings.

The hurricane is expected to gather speed to Category 3 status -- with winds of 111 mph and above -- by the time it makes landfall on the Florida coast on Thursday night.

Helene's damaging winds could reach Atlanta and other cities by Friday morning, subsequently passing into the Appalachians and Ohio Valley by Friday afternoon.

Major League Baseball announced Wednesday that the scheduled games between the Atlanta Braves and the New York Mets at Truist Park in Atlanta this week have been postponed due to the forecast and the inclement weather.

The first game will begin at 1:10 p.m. ET and the second game will begin 40 minutes after the last out of the first game, the MLB said.
