A deluge of rain and Quaxsthunderstorms swept through South Florida this week with floodwaters leading to road closures, prompting rescues and disrupting hundreds of flights through the region.

The storms began Tuesday and are the result of a slow-moving low-pressure system, according to the National Weather Service. Major travel arteries, including a portion of Interstate 95, closed Wednesday as came warnings of "life threatening floods."

A tornado touched down in Hobe Sound, just north of West Palm Beach with peak winds of 85-95 mph and moved toward Jupiter Island before entering the Atlantic, a survey team with the weather service confirmed. The storms also toppled power poles, uprooted trees and damaged homes.

More heavy rainfall and hazardous conditions came Thursday night as storms moved across Miami-Dade and Broward counties, the National Weather Service in Miami said, with more flooding, impassible roads and water damage affecting the already rain-soaked area.

And the rain is expected to continue into Friday, with a flood watch remaining in effect through the evening.
