NEXT Weather Alert: Strong storms, flood risk possible for South Florida this weekend
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." Storm timing and severity vary through the weekend Weather outlook for Saturday. CBS News Miami 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. Looking ahead to midweek, a new surge of Saharan dust may push in from the Caribbean. CBS News Miami No marine alerts are currently in effect.

Severe weather threat could lead into Memorial Day weekend in Miami
South Florida could give a wild introduction to Memorial Day weekend before offering up a relatively normal summer-like day — heat and chance of storms — on the Monday holiday. On Thursday, the National Weather Service in Miami said there's a marginal risk for isolated strong to severe storms for the eastern half of South Florida Thursday and Friday afternoons between 2 and 10 p.m. The risk level was 1 on a 5 scale, meaning the severe storms would be isolated. As the scale climbs the area of storm coverage expands. On Thursday, the Miami weather service also issued its outlook for the 2025 South Florida rainy season, calling for a 'slight favoring of above normal rainfall, and likely above normal temperatures through the summer.' Possible hazards Threat: The strongest storms could include isolated strong to severe winds and marginally severe hail — not gorilla hail of two or more inches in size, but possibly large hail up to an inch. 'An isolated tornado can't be ruled out,' the service said in its forecast. Heavy rainfall could also result in localized flooding. Timing: The highest rain and thunderstorm chances in the Miami and Fort Lauderdale areas stretch from 3 p.m. to 8 p.m. Thursday and 11 a.m. to 7 p.m. Friday. Some rain and thunder are forecast for 3 to 5 p.m. Saturday and 9 a.m. to 5 p.m. Sunday. Memorial Day: On the Monday holiday, the biggest rain chance is from 8 a.m. to 8 p.m. but well under an inch. If thunderstorms roll in, the highest chance is from 2 p.m. to 7 p.m. Area: The marginal risk area for these severe storms extends from south of Homestead to north of West Palm Beach and includes Miami, Fort Lauderdale, Boca Raton, Belle Glade and Clewiston. Areas outside the marginal risk section could still experience some isolated thunderstorms. These locations include the Florida Keys, Naples and Tampa. Key West is looking at rain and storm chances at 10% through Saturday, according to the weather service, bumping to 20% Sunday and Monday. If you're traveling to Orlando's attractions for the three-day weekend, there's a 20% to 30% rain or storm chance Thursday through Sunday. But chances bump up to 50% after 2 p.m. on Memorial Day Monday. Heat KNOW MORE: Feeling dizzy? Watch for these warning signs during South Florida's heat wave Threat: Expect an elevated heat risk in the same regions that are expecting storms. That's south of Homestead up the east coast, taking in Miami-Dade and Broward, beyond Jupiter and expanding to Naples on the Gulf Coast of Florida. An elevated heat risk means heat index readings — the 'feels-like' temperature — of 103 to 107 degrees. These figures would have to hit and hold 105 for at least two hours to trigger a heat warning in Miami-Dade. As of Thursday morning, warnings and alerts had not been issued. Miami Herald news partner CBS News Miami reported even higher temperatures coming. Meteorologist Ivan Cabrera forecasts low- to mid- 90s Thursday with a heat index in the triple digits. Memorial Day highs and heat indexes in the Miami area Monday run about 86 and 'feels-like' 96 between 11 a.m. and 5 p.m. Saturday and Sunday should feel about the same, with Saturday peaking at a high of 87 with an index of 98 at 2 p.m., according to the Miami weather service. Key West's forecast is similar, with highs in the upper-80s, near 90. Orlando expects highs in the mid-90s Monday. Naples is looking at 90, with a 50% rain or storm chance on the holiday. Tips: To avoid heat stroke and heat exhaustion and sunburn, drink plenty of water, electrolyte-rich sports drinks or juice. Wear protection like loose, light-colored clothing and apply sunscreen. Don't leave people or pets sitting inside parked cars while you run into stores, especially with the AC off. Make sure your pets have plenty of water and shade.

NEXT Weather Alert Days The NEXT Weather Team has issued NEXT Weather Alert Days for both Thursday and Friday due to the potential for strong to severe afternoon storms. The main concern will be storms which could contain damaging wind, hail, and isolated heavy downpours. NEXT Weather Chief Meteorologist Ivan Cabrera said a frontal boundary will get an atmospheric kick and push toward the southeast across Florida on Thursday. A pocket of deeper atmospheric moisture will move in with the front and bring showers and storms back into the picture. A southwesterly flow, along with a pinned sea breeze, will act to focus showers and storms along the coastal metros. NEXT Weather Alert Days for Thursday and Friday. NEXT Weather The Storm Prediction Center has Broward County and the Miami-Dade metro area at a marginal risk for isolated strong storms on Thursday and Friday afternoons. The storms will form primarily in the afternoon and early evening hours.

Next Weather Alert Day issued for South Florida Tuesday as heavy rain, flood threat loom
South Florida is bracing for a soaking Tuesday as the CBS News Miami Next Weather team has issued a Next Weather Alert Day , warning of potentially heavy rainfall, street flooding and isolated strong storms expected to impact the region through the afternoon and evening hours. Two low-end weather threats, damaging winds and flash flooding, are forecast to develop as a cold front moves across the region, bringing deep tropical moisture, gusty winds and scattered thunderstorms. The front, which has already brought severe weather and flooding to parts of the Southeast, is expected to arrive in South Florida by midday Tuesday. CBS News Miami's chief meteorologist Ivan Cabrera said that while the system has a history of producing severe weather farther north, South Florida's main concern will be flooding rains between noon and 4 p.m. "This front could produce some intense downpours in a short amount of time," Cabrera said. "Some isolated storms could dump 1 to 3 inches of rain very quickly, especially across coastal Broward, Miami-Dade, and the Upper Keys." The CBS News Miami Next Weather team is also watching for the possibility of damaging wind gusts in far southeastern Miami-Dade and the Upper Keys. While severe weather ingredients are not as strong in South Florida as they were up north, a few strong cells could still develop along and ahead of the front. Ahead of the front, South Florida will see breezy south-southwest winds and sunshine Monday, with highs in the mid-to-upper 80s. But by Tuesday afternoon, widespread showers and thunderstorms are expected to sweep through the area. Whether or not flash flooding fully materializes will depend on the development of the East Coast seabreeze, which could stall storms over the metro areas. If that happens, rainfall totals could climb as high as five inches in some isolated spots. By Wednesday, the front will clear the region, leaving behind only scattered showers. Thursday and Friday will bring drier weather as leftover moisture begins to exit the area. Looking ahead to the weekend, a second, late-season cold front is forecast to move in, delivering unseasonably dry and cool air to South Florida. Highs will fall into the low 80s, while overnight lows could dip into the 60s—and even the 50s in some inland spots Sunday morning. "This weekend is going to be absolutely beautiful," Cabrera said. "We're talking sunshine, low humidity and cool mornings, really picture-perfect spring weather."

Smoke from brush fire could lower air quality over parts of Miami-Dade, upper Florida Keys
A Next Weather Smoke Alert has been issued Wednesday for southern Miami-Dade County and the upper Florida Keys due to the potential for smoke reducing air quality after sunset and continuing overnight. Radar continued to show significant smoke plumes with no signs of dissipating. The smoke originated from a massive brush fire in southern Miami-Dade County , which has already burned 3,600 acres and remained only partially contained as of Wednesday, according to the Florida Forest Service. Fire crews, including more than 15 Miami-Dade Fire Rescue units and personnel from the Florida Forest Service, continued efforts Wednesday to contain the flames. According to First Weather Alert meteorologist Ivan Cabrera, shifting winds could push smoke into different areas of South Florida, creating hazardous air conditions. Drivers in the affected regions are advised to keep vehicle windows rolled up and use air conditioning in recirculation mode to limit exposure to smoke, Miami-Dade Fire Rescue said. The fire has also caused major traffic disruptions. Card Sound Road remained closed Wednesday, and U.S. 1's 18-Mile Stretch, which was shut down Tuesday, reopened late that night but continued to experience delays as fire crews intermittently blocked traffic for firefighting efforts. The Monroe County Sheriff's Office cautioned drivers to expect ongoing travel disruptions. A fire weather warning will go into effect at 11 a.m. Thursday, as winds are expected to pick up ahead of an approaching front, creating conditions for rapid fire spread. Officials said the lack of rain in the forecast and persistent dry conditions could further fuel the wildfire. The Florida Highway Patrol said Wednesday morning that the fire is expected to burn for several days .
