Broward and Miami-Dade counties are currently experiencing a heatwave, with an excessive heat warning in effect until 6 p.m., issued by the National Weather Service. This warning is triggered when heat index values are expected to reach 110 degrees or higher for a minimum of two hours. At 8:46 a.m., the National Weather Service upgraded the initial heat advisory to an excessive heat warning due to high temperatures ranging between 108-112 degrees, with feels-like temperatures potentially reaching up to 113 degrees. This intense heat is forecasted to persist for at least two hours this afternoon.
In addition to Broward and Miami-Dade counties, the Florida Keys are also under a heat advisory until 7 p.m., with feels-like temperatures projected to soar to 109 degrees. The National Weather Service has emphasized the importance of staying informed about weather alerts to ensure the safety and well-being of residents in these areas.
The occurrence of an *Excessive Heat Warning* is a rare event, with the threshold temperature being challenging to achieve. The National Weather Service in Miami recently issued the first excessive heat warning of 2024, following a total of six warnings in 2023, with the most recent one being over a year ago in early August. Meteorologist Ryan Phillips shared this information, highlighting the significance of staying vigilant during extreme weather conditions.
Fort Lauderdale and Miami have been experiencing record-breaking temperatures, with Fort Lauderdale tying a record-high temperature of 93 degrees on Friday, matching the previous record set on Sept. 13, 2015. Miami reached 95 degrees, falling just shy of the record of 96 degrees set the previous year. The forecast for Saturday indicates a continuation of near-record heat, with temperatures expected to range from the low to mid-90 degrees. Miami is forecasted to reach 93 degrees, close to the current record of 94 degrees, while Fort Lauderdale’s record of 98 degrees set in 1955 remains out of reach.
As the day progresses, there is a possibility of thunderstorms developing in the region. With a westerly wind component, the storms are likely to initiate inland before moving eastward in the afternoon and evening. The heavy rain associated with these storms could lead to additional flooding in areas with poor drainage systems, potentially causing localized ponding. NBC6’s Chelsea Ambriz provides a detailed forecast for Saturday, advising viewers to stay informed and take necessary precautions.
The Red Cross and the National Weather Service have outlined several recommendations to help individuals cope with high temperatures and prevent health issues during periods of extreme heat. It is essential to stay hydrated, wear lightweight clothing, and protect oneself from the sun while engaging in outdoor activities. A critical warning is to never leave children or pets in a vehicle, as the interior temperature can quickly reach lethal levels. Limiting consumption of caffeinated or alcoholic beverages, seeking shelter in air-conditioned spaces during peak heat hours, and avoiding strenuous outdoor activities are also advised to mitigate heat-related risks.
Looking ahead, Sunday is expected to mirror Saturday’s weather conditions, with a slight decrease in storm coverage but continued afternoon showers and storms. Temperatures are forecasted to remain in the low 90s, with unsettled weather patterns persisting throughout the coming week. Tropical Storm Gordon remains in the Atlantic Ocean, posing no immediate threat to land as it moves into drier, more stable air with significant wind shear, potentially weakening back into a tropical depression. Another area of interest off the U.S. coast shows a low chance of development in the next two days and a medium chance of development in the next seven days. This system is expected to evolve into a subtropical depression as it interacts with the Gulf Stream, with the potential for tropical development in the following week.
In conclusion, staying informed and prepared for extreme heat events is crucial for ensuring the safety and well-being of individuals in Broward, Miami-Dade, and the surrounding areas. By following the recommendations provided by the Red Cross and the National Weather Service, residents can effectively navigate the challenges posed by high temperatures and minimize the risk of heat-related illnesses. As the weather continues to fluctuate, it is essential to stay updated on the latest forecasts and advisories to stay safe during periods of extreme heat.
