MIAMI – A heat advisory was issued for Miami-Dade, Broward and the Keys on Wednesday as perceived temperatures (which take humidity into account) could reach as high as 109 degrees in the afternoon.

Maximum temperatures will be just over 30 degrees under predominantly sunny skies. A breeze from the east will direct the storms inland and to the west.

The National Weather Service says there is a moderate risk of rip currents along Atlantic beaches as a steady onshore current prevails. The rip current risk is likely to become high along Atlantic beaches Thursday as the onshore current persists and a north-northeast swell develops.

There are no warnings or advisories for boaters in the Atlantic Ocean and Keys, but the swell is moderate and the waves are 2 to 3 feet (60 to 90 cm).

On Thursday and Friday, the chance of rain will decrease as drier Saharan air moves in. With less rain and cloud cover, it will be hotter with highs reaching just above 30 degrees. When you factor in the humidity, it will feel like triple-digit temperatures. A few showers and isolated thunderstorms cannot be ruled out, but things will calm down towards the end of the week as the Saharan dust will suppress the development of widespread thunderstorms.

Rain chances increase slightly this weekend, and a few showers and thunderstorms are possible on Saturday and Sunday. It will remain hot and humid, with seasonal highs around 35 degrees and a heat index around 38 degrees.
