MIAMI (CBS4) — A wet and windy weekend is in store for South Florida as strong high pressure to the north and a developing low pressure area to our south combine forces.

Late Friday, the National Weather service issued a flood watch for all of South Florida until Sunday.

Large portions of South Florida could see 3 to 6 inches of rain over the weekend. A few spots might see even heavier amounts.

CBS4’s David Bernard advises to never attempt crossing waters of unknown depth on foot or while driving.

The low pressure system is forecast to move slowly north near South Florida this weekend producing periods of very heavy rain and strong wind gusts to near 50 mph.

Besides the possibility for flooding, the strong eastern winds will create dangerous beach and boating conditions.

Already some parts of South Florida have seen wind gusts over 40 mph and the gusty winds are expected to last for most of the weekend.

There is also the potential for some severe weather especially Saturday night and into early Sunday.
