South Florida is preparing for a significant heat wave after experiencing heavy rain and a tornado. CBS News Miami reported that the region received up to 4 inches of rain recently, and now the skies have cleared. However, this transition brings a new challenge: a prolonged period of hot, sunny weather. Residents should expect afternoon showers on Monday, followed by consistently high temperatures throughout the week. The heat wave is expected to bring above-average daytime highs, leading to heat advisories to protect public health. Local authorities are advising residents to take precautions to reduce the risks associated with extreme heat.
