Drier air reduces the chance of rain in South Florida
The prevailing weather this afternoon in South Florida will be sunny to partly cloudy. Bertha’s movement is responsible for the entry of a mass of drier air, which considerably reduces the probability of precipitation. However, communities located further inland in the region may still experience isolated rain and thunderstorms. The population should prepare for moderate winds coming from the south and southeast.
High temperatures and intense thermal sensation mark the day
Maximum temperatures in the region should reach levels between 32°C and 35°C. The thermal sensation, a crucial factor for health on hot days, can easily exceed 37°C. This combination of high heat and perceived humidity demands attention, especially for those planning outdoor activities. It is essential to stay hydrated and avoid prolonged exposure to the sun during peak times.
