Tropical Storm Debby is gaining strength and is now expected to make landfall on the west coast of Florida as a Category 1 hurricane.

According to the National Hurricane Center, Tropical Storm Debby formed off the northwest coast of Cuba on Saturday and would move into the Gulf of Mexico overnight. The storm slowed as it passed over Cuba, allowing it to gain strength and delaying landfall in Florida until approximately 2 a.m. Monday.

“Based on the current forecast, Alachua County residents and visitors should complete all storm preparations by no later than mid-afternoon Sunday,” the county said in an 8 p.m. update.

The National Hurricane Center predicts 6-12 inches of rain in a widespread area of the Suwannee River Valley—with some areas seeing as much as 18 inches.

“Alachua County is forecast to receive 5-8 inches of rain between Sunday and Monday,” the county said in its evening update. “Winds and rains adding to the already saturated conditions, could lead to an increase in downed trees and power outages across our area.”

Both the city of Gainesville and Alachua County have declared states of emergency ahead of the storm. The city reported distributing some 4,000 sandbags on Saturday.

So far, the county has not announced any emergency shelter operations.

Alachua County has activated its 311 emergency information line, which is also available at 352-264-6557 for questions and rumor control. To sign up for emergency alerts, text ALACHUA to 888-777.
