Heat advisories issued for southern Florida.

The states of Texas and even the southern part of Florida have received a heat advisory due to the high temperatures recorded in their cities this weekend.

Only in Miami, temperatures close to 90 degrees Fahrenheit (32 degrees Celsius) were recorded before noon, according to AP.

This is due to the abundant sunlight and the relatively late onset of any rain and storm activity," explained the National Weather Service in Miami (NWS).

This Sunday, the meteorological entity forecasts a warm day, with rain and storms, as an upper-level disturbance moves through the area.

Excessive heat warnings are not limited to the mentioned states but extend to the eastern half of Oklahoma, northern Louisiana, and most of Arkansas, where high temperatures close to and above 100 degrees F (38 degrees C) are forecasted, with heat indexes of 110 to 115 degrees F (43 to 46 degrees C), as reported by AP.

The eastern part of Mississippi and Tennessee, including Memphis, also have chances of experiencing hot days.

The NWS had warned days earlier that excessive heat "can be dangerous if you plan to leave the comfort of air conditioning and are not prepared for outdoor activities."

Excessive heat warnings are issued when the heat index is expected to reach 105 degrees (40 degrees Celsius) for at least two hours.

With these temperatures, people are more susceptible to fatigue, heat exhaustion, and even heatstroke.

The main recommendations are: drink plenty of fluids and stay away from the sun as much as possible for the duration of the warning.

Paradoxically, the NWS also issued three flood alerts in the metropolitan counties of Broward, Miami-Dade, and southern Palm Beach this Sunday.

"They definitely mentioned that it is not an ideal climate for driving, so be very careful."
