Tropical Storm Debby has intensified in the Gulf of Mexico and is expected to make landfall as a hurricane in Florida's Big Bend region Sunday night, potentially bringing historic rainfall and catastrophic flooding. Authorities have ordered partial evacuations along the Gulf Coast, particularly in Citrus County, with mandatory evacuations implemented in some areas. Florida Governor Ron DeSantis has mobilized 3,000 National Guard members as part of emergency preparations, highlighting the life-threatening nature of the storm. The National Hurricane Center predicts severe weather impacts, including tornado warnings and storm surge risks of up to 7 feet along the coast. Central Florida is already experiencing heavy rain and the threat of tornadoes, with the worst conditions anticipated through Monday afternoon. Residents are urged to seek shelter and adhere to evacuation orders as Debby approaches.
