Topical Storm Ian is expected to strengthen rapidly this weekend and approach Florida at or near major hurricane strength early next week, according to the National Hurricane Center.

Ian is moving toward the west near 15 mph and this general motion is expected to continue through tonight. The forecast shows Ian becoming a hurricane by late Sunday and approaching western Cuba at or near major hurricane strength by Monday night. Due to limited land interaction, Ian is expected to be a major hurricane over the eastern Gulf of Mexico on Tuesday and Wednesday as it approaches the west coast of Florida.

Ian is moving over very warm waters and it should not take long for the system to develop an inner core. Once that happens, rapid intensification is expected while Ian crosses the northwestern Caribbean Sea.

Gov. DeSantis declared a preemptive state of emergency on Friday for 24 Florida counties.
