MIAMI (CBSMiami) – Expect very quick changing weather conditions on Sunday.

The outer bands of Tropical Storm Debby continue to bring fast-moving storms to South Florida. Many of these storms have built-in rotation and thus isolated, fast-moving tornadoes are possible.

This pattern will continue through the day and into tonight because Debby is basically stalled in the Northern Gulf. That means you should expect fast-moving, hit and miss storms for the next 24 hours along with plenty of dry breaks as well.

The Golden Beach police department reported that a waterspout came ashore in the 400 block of Ocean Boulevard at 2:05 p.m.  The debris field was spread along a six block area.  Damage included a garage door being blown open and number of trees down.

CBS4 meteorologist Jeff Berardelli says Tropical Storm Debby is forecast to slowly drift north over the next 48 hours. After that the forecast remains very uncertain as some computer models push the storm east across Northern Florida while others take it to the West or Northwest into the western Gulf.

While the track is very uncertain after the next two days, Berardelli says the impacts to South Florida are not. We will continue to see outer bands of Debby with periodic, fast-moving storms and isolated tornadoes. Thus the weather here will stay stormy through at least the early week.
