Jacksonville is at an increased risk for tornadoes starting Sunday, according to the National Weather Service. Extensive tree and structural damage is expected throughout Duval County.

The biggest threat to Duval County is wind damage followed by flood damage, with high speed winds and a storm surge of 1-3 feet  threatening the first coast. According to the NWS, Jacksonville should expect 1-3 feet of storm surge on the St. Johns River, especially near Riverside.

Those along the coast can expect wind gusts up to 80 mph and 10 to 15 inches of rain.

Mayor Lenny Curry is encouraging those that are still in an evacuation zone to seek shelter now. Shelters are only at 10% capacity, Curry said in a press conference.

During the storm, Curry is asking residents with non-medical emergencies to call (904) 630-0500. For medical emergencies, call 911.

Sheriff Mike Wiliams said at some point, first responders will likely have to wait for Hurricane Irma to subside before providing help.

Bridges will likely shut down sometime tomorrow when wind speed reaches 40 mph. Williams said when bridges shut down, expect them to be shut down for at least 12 hours.

Curry is asking residents to finalize where they will be staying for the storm by 8 p.m. Saturday.
