While the National Hurricane Center continued its confidence that there would be no tropical activity in Atlantic areas for the next week, Saharan dust and a few tropical waves were what forecasters watched Saturday.

The real impact for Florida on Saturday will come from the heat. The entire Florida peninsula can expect triple-digit heat indexes with some in Southwest Florida predicted for 110 degrees, and 106 as far north as Jacksonville. Heat advisories are in effect for seven South Florida counties.

A wave of Saharan dust is expected to arrive in South Florida Saturday morning and move north, arriving around Cape Canaveral by Sunday. The dust is expected to be thickest in South Florida, dissipating as it moves north.

Tropical moisture may increase Florida’s rain chances starting Monday, but, according to Ryan Truchelut, chief meteorologist at WeatherTiger, it won’t be anything organized. Saharan dust, high wind shear and other factors are expected to keep the tropics quiet for the days ahead.

The Hurricane Center is monitoring three tropical waves.

The peak of hurricane season runs from mid-August through mid-October. If your hurricane supplies are running low, or you haven’t started an emergency kit, Florida’s next sales tax holiday the end of August can help you save money.

Possible impact of tropical wave on Florida

A tropical wave is expected to approach the Florida peninsula Sunday, bringing downpours and gusty thunderstorms. A couple of waterspouts could occur, according to AccuWeather.

“As the tropical wave approaches and moves northwestward across the state from Sunday to Tuesday, an uptick in the showers and thunderstorms will occur with the potential for some to bring flooding downpours, strong wind gusts and even waterspouts near the beaches,” AccuWeather Lead Hurricane Expert Alex DaSilva said.

The tropical wave is not forecast to develop into a tropical depression or a named tropical storm.

How long will tropics remain quiet?

The Saharan dust and winds are keeping the tropics quiet now, but forecasters say that will likely change.

“The favorable conditions that yielded Beryl are likely to return at some point in August, and that will probably yield an extended burst of hurricane activity,” said Dr. Ryan Truchelut, chief meteorologist at WeatherTiger.

“WeatherTiger’s real-time forecast remains for around twice the amount of storm activity in a normal hurricane season.”

The next storm of the season will be Debby.

What is NOAA tracking in Atlantic basin?

The National Hurricane Center said no tropical cyclone activity is expected over the next several days.

Elsewhere in the tropics, the National Hurricane Center is monitoring three tropical waves. Here’s the latest update from the NHC as of  8 a.m. July 20:  

• Tropical wave 1: An eastern Atlantic wave was identified via satellite imagery. It’s producing some showers.
• Tropical wave 2: In the central Caribbean, this wave is expected to move from the Windward Passage to northern Colombia and helping to induce scattered to numerous showers with embedded thunderstorms over Hispaniola and regional waters as well as across the Windward Passage and the waters between eastern Cuba and Jamaica. These storms may produce heavy downpours, lightning and gusty winds.
• Tropical wave 3: Another tropical wave over the Yucatan Peninsula and Guatemala is moving westward and producing scattered showers and may produce gusty winds or stronger storms in parts of the region.

Who is likely to be impacted? 

A tropical wave is expected to bring tropical moisture to Florida starting Sunday.

Forecasters urge all residents to continue monitoring the tropics and to always be prepared. That advice is particularly important for what is expected to be a very active hurricane season.
