A NEXT Weather Alert is in effect for South Florida from noon to 6 p.m. Saturday as isolated strong to severe storms are expected to roll across the region, CBS News Miami Chief Meteorologist Ivan Cabrera said.
The alert comes as a frontal boundary moves into the area Saturday and stalls through the weekend, combining with a mid-level disturbance and ample tropical moisture to create unstable conditions.
Cabrera emphasized the threat is not widespread, classifying it as a Level 1 out of 5, but warned that marginally severe storms could still develop.
"With daytime heating, sea breeze interactions, and an incoming front, we could see strong gusty winds, brief hail, and heavy downpours Saturday afternoon into the early evening," Cabrera said. "Localized flooding is possible where storms linger."

The Saharan Air Layer (SAL), a dry, dusty mass of air from Africa, could suppress storm development earlier in the day but is not expected to prevent storms from forming entirely, Cabrera added.
Sunday is forecast to be slightly less active, though one or two strong storms could still pop up in the afternoon. Both days could bring heavy rainfall, and the deep tropical moisture in the atmosphere means even brief storms may produce significant rainfall totals.
Temperatures are expected to reach the lower 90s Saturday and Sunday before rain cools things off.
More storms, possible alerts early next week
By Monday, the frontal boundary is forecast to remain stalled, and a strengthening disturbance could trigger another round of strong storms with localized flooding potential. Additional NEXT Weather Alerts may be issued.
Looking ahead to midweek, a new surge of Saharan dust may push in from the Caribbean, possibly limiting storm coverage. However, high chances of showers and storms remain in the forecast through at least Wednesday.
