Miami, FL — South Florida is under a heat advisory today as residents brace for oppressive temperatures and a chance of thunderstorms throughout the week. The National Weather Service warns that heat index values could soar to 107 degrees across Miami-Dade and Broward counties from 10 a.m. to 6 p.m. Monday. Hot temperatures and high humidity are expected to create dangerous conditions, particularly for those spending extended time outdoors.
In addition to the intense heat, residents should prepare for thunderstorms, which are forecasted to persist into the weekend. According to the National Weather Service, a slight chance of showers and thunderstorms will continue Tuesday afternoon, with a 20% chance of precipitation before 2 p.m. Thunderstorms will increase in likelihood by Wednesday, carrying a 30% chance of afternoon storms. Areas near major roadways, such as I-95 and I-75, could experience localized flooding due to sudden downpours, creating hazardous driving conditions.
By Thursday and Friday, chances of thunderstorms will rise to 40% to 50%, with the possibility of heavy rain and gusty winds. While daytime temperatures will hover in the upper 80s, the heat index could remain in the triple digits, keeping outdoor conditions risky. Thursday night and Friday will see temperatures drop to the low 80s, but the risk of thunderstorms will persist, particularly during the afternoon and early evening hours.
The Occupational Safety and Health Administration (OSHA) recommends that workers and residents limit strenuous outdoor activities, stay hydrated, and wear lightweight, loose-fitting clothing. Heat-related illnesses, such as heat stroke, are a significant concern. If you or someone nearby shows signs of dizziness, confusion, or nausea, move to a cooler location and seek immediate medical attention.
Residents should continue monitoring local weather reports for updates, as conditions may shift throughout the week. Thunderstorms could cause disruptions, especially during peak travel hours on heavily used routes like I-95 and US-1.
