On Friday, Tampa hit a high of 99 degrees Fahrenheit, which is the highest ever temperature for any date.
Florida is no stranger to heat and humidity, especially in summer.

But this last winter was another in a series of nine warmer-than-average winters, and this summer continues that series.
When you factor in the humidity, the temperatures you can feel are around 30 ° C (110 ° F), which gets into the dangerous area.
In large parts of the western half of the peninsula, heat warnings are in effect again today. Temperatures will be a degree or two through Monday but will remain above average.
Much of the south, including Florida, has experienced the most significant levels of Saharan dust in over 50 years.
It is not uncommon for dust particles from the Sahara desert of Africa to travel across the Atlantic to the eastern United States, but this event was more extreme than most people living in the south have ever experienced. It will fade a bit tomorrow but will return by the middle of the week.

People with breathing problems need to take precautions.
Saharan dust makes for some beautiful sunsets and sunrises and also depresses thunderstorm development, reducing the likelihood of tropical storms and hurricanes developing in the Atlantic Basin.
