UPDATE: South Florida upgraded to slight risk of severe weather.
National Weather Service forecasters are warning of a marginal risk for severe weather in South Florida today as the cold front of a low pressure system moves through the area.
On Saturday night, another low pressure system is expected to hit South Florida, bringing more storminess.
Strong to possibly severe storms are expected this morning across southwest Florida and Lake Okeechobee as the front moves in from the Gulf of Mexico.
More storms with strong and gusty winds up to 60 mph will move across the entire South Florida area this afternoon.
NWS forecasters issued a high risk of rip currents this morning, which remains in effect at least through the afternoon. They are also alerting to the possibility of minor and isolated street flooding.
Chances of rain today are 90 percent.
Isolated tornadoes cannot be ruled out. Waterspouts over coastal waters, which could impact approach for airports, are also possible.
The storms today are getting a boost from the subtropical jet stream, which is rushing at more than 115 mph, according to the NWS in Miami.
The threat of strong and severe storms is slightly higher this afternoon with low-level winds increasing. Although the main concern is damaging straight-line winds, there is also the threat of tornadoes from both small cells ahead of the main line of storms, as well as storms embedded in the main frontal boundary.
