Hurricane Isaias strengthened to a Category 3 storm Friday morning, with landfall expected on the Florida Panhandle between 8 p.m. and 10 p.m. EDT. A hurricane warning is in effect from east of Biloxi, Mississippi, through Mobile and Pensacola, extending to Panama City and Mexico Beach, Florida.

Communities along the U.S. Gulf Coast are bracing for the powerful storm, which has prompted widespread evacuations in low-lying and coastal areas, particularly on the Florida Panhandle. Residents are preparing for strong winds that could reach speeds close to 120 mph in some locations, according to Florida Gov. Ron DeSantis.

Storm surge warnings are also active along the coast. Forecasters predict surges could reach up to 9 feet in some areas, specifically from the Santa Rosa/Okaloosa County Line to Grayton Beach, Florida. The National Hurricane Center officially upgraded Isaias to a major Category 3 hurricane at 8:20 a.m. ET.

Escambia County Public Safety Director Eric Gilmore urged residents in the Northwest Florida county, which includes Pensacola, to complete their preparations quickly. Gilmore emphasized during a press conference Friday morning that residents should be in their safe spaces by noon.

Florida officials, including Governor DeSantis, have stated that the state is taking the threat of Hurricane Isaias very seriously. "The resources have been flowing, the preparations have been extensive, and we are taking this storm very, very seriously," DeSantis remarked ahead of the anticipated landfall.

Residents were seen taking last-minute precautions, such as boarding up storefronts in Pensacola Beach and filling portable gas containers at local stations. The approaching storm has created a sense of urgency as communities finalize their readiness.

The National Hurricane Center's upgrade signifies a significant increase in the storm's intensity, elevating concerns about potential damage from high winds and coastal inundation. The Category 3 designation means Isaias now carries sustained winds of 111-129 mph.

Further updates on the storm's track and intensity are expected as it continues its approach to the coast. Emergency management agencies are coordinating response efforts and providing guidance to affected populations.
