Saharan dust approaching from the east is expected to arrive in South Florida today, bringing drier air, according to the National Weather Service Miami.
Don't expect the dust to reach the west coast before showers and storms arrive.
That dust is helping keep the tropics quiet. The dust, along with wind shear, helps prevent storms from developing and strengthening.
➤ Track all active storms
No disturbances were highlighted on the tropical outlook map this morning, according to the latest advisory from the National Hurricane Center .
Forecasters are monitoring three tropical waves, including one in the Caribbean.
Historically, 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.

How long will tropics remain quiet?
"There is a lot of dry air and dust moving off of Africa and spreading across the Atlantic" said Alex DaSilva, AccuWeather lead hurricane expert.
"With all the dust and dry air around, it will make it very difficult for anything to develop over the next 7-10 days. There are signs that at the very end of the month and into the start of August, the dry air may begin to back off and atmospheric conditions are looking a little more favorable for tropical development."
Where do July storms usually develop?
"This could also be the time of year when development can start to occur all across the entire basin," DaSilva said.
"Usually — Beryl was a huge exception — early in the season there is almost no development east of the Lesser Antilles. As we move into August, we need to start watching the tropical waves moving off of Africa as they can develop more quickly as we get later into hurricane season."
Rapid intensification of hurricanes concerning
Rapid intensification is an increase in wind speeds of about 35 mph over 24 hours.
"I am still very concerned about rapid intensification as we move later into the summer. One of the main reasons Beryl was able to become a Cat 5 was because of the record-breaking warm waters for this time of year across the Main Development Region," DaSilva said.
"These water temperatures are only going to increase from here, making the basin prime for rapid intensification. I think that as long as we continue to see sea-surface temperatures increasing across the Atlantic, rapidly intensifying storms are something we are going to deal with as we move into the future," DaSilva said.
What are chances of hurricane impacting Florida?
"Since our forecast was released in March , we have been concerned about the Texas coast, Panhandle of Florida, South Florida and the Carolinas as having an increased chance of tropical impacts," DaSilva said.
➤ Will hurricane hit Florida during 2024 season?
"We continue to be concerned about those areas. Everyone living in hurricane areas should always have their hurricane plans ready to go.
"We're still expecting a very, very busy season ," DaSilva said. "Don't let your guard down. Don't be fooled by the quiet period. We're at the very beginning of hurricane season. It will ramp up and it could ramp up very quickly."
The next storm of the se ason will be Debby.
Here's the latest update from the NHC as of 8 a.m. July 16:
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:
- Tropical wave 1: A tropical wave in the central Atlantic is moving west at 6 to 11 mph.
- Tropical wave 2: A tropical wave in the western Atlantic extends from Barbados to northern Suriname. It's moving west at 17 to 23 mph.
- Tropical wave 3: A tropical wave in the western Caribbean extends from the Gulf of Mexico across Honduras and Nicaragua into the eastern Pacific. It's moving west at 23 mph.
Who is likely to be impacted?
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.
