All the tropical activity for June 11 is staying well away from Florida. So far, all storms have developed in the eastern Pacific.
In the Atlantic basin, the National Hurricane Center is watching three tropical waves, including one in the Caribbean.
The Atlantic is likely to remain quiet through the end of June, despite some early hints at tropical formation, according to AccuWeather.

In the eastern Pacific, though, there are the remains of former Hurricane Barbara, Tropical Storm Cosme, a system of low pressure expected to strengthen into a tropical depression by the weekend and now, another disturbance west of Central America showing a low chance for development over the next seven days.
Another large plume of dust moving across the Atlantic could reach Florida around June 13, according to AccuWeather. Dust, along with wind shear, help suppress tropical development.
Here's the latest advisory from the National Hurricane Center as of 8 a.m., June 11:
The National Hurricane Center is monitoring three tropical waves in the Atlantic:
Tropical wave 1: An eastern Atlantic tropical wave is near 24W from the eastern Cabo Verde Islands southward, and moving west at 11 to 17 mph. Scattered moderate convection is occurring from 04N to 09N between 21W and 28W.
Tropical wave 2: A central Atlantic tropical wave is near 52W from 16N southward, and moving west near 17 mph. Scattered moderate convection is observed from 05N to 09N between 50W and 53W.
Tropical wave 3: An eastern Caribbean tropical wave is near 66W, moving west around 11 mph. Scattered moderate convection is occurring over central Venezuela.
"The average first named storm in the Atlantic is June 20, but development over the central and eastern basin looks unfavorable through June at this time," said AccuWeather Lead Hurricane Forecaster Alex DaSilva.
"We still expect the Central American gyre to form later this month, and its formation could spur tropical development in waters in the western Caribbean or southwestern Gulf."
Now is the time to prepare for a hurricane, before a storm is approaching.
After becoming the first hurricane of the 2025 season in the eastern Pacific on June 9, hours later Barbara quickly weakened back into a tropical storm June 10 and was a post-tropical cyclone by June 11.

Tropical Storm Cosme continues to weaken and is expected to become a remnant low later this morning, June 11, and dissipate by late June 12 or June 13.
Southeast of Cosme is an area of low pressure expected to strengthen into a tropical depression over the weekend. Chances for development has increased to 90% over the next seven days.
A new area being watched by forecasters is located west of Central America. It has a 20% chance for development over the next seven days.
Historically, tropical cyclones form close to the U.S. in June, with the most common locations being the northwestern Caribbean and the eastern Gulf, according to Dr. Ryan Truchelut, chief meteorologist with WeatherTiger. Truchelut is a Florida meteorologist who works with the USA TODAY Network.
"None of the reputable forecast models are showing a realistic chance of anything tropical forming on the Atlantic side of Central America through mid-month."

The exception is the GFS model, which is predicting a Caribbean tropical storm will spin up in 10 to 12 days, then move generally northward, Truchelut said.
"The GFS has a persistent and well-known bias for incorrectly predicting development in the Caribbean at this specific time of year," Truchelut said. "All told, while something could eventually spin up in two or three weeks, the GFS' frequent false alarms should be disregarded."
A "ghost hurricane" is a term used to describe a tropical storm or hurricane that appears in a forecast model but which doesn't happen in reality, according to CNN.
Pensacola, western Panhandle: Showers and thunderstorms are likely, mainly between 1 p.m. and 4 p.m. High near 86.
Tallahassee, central Panhandle: The wet pattern continues today, and it is likely to continue into the weekend and early next week. Daily chances for showers and storms are expected, especially across inland areas. High near 92, with heat index values as high as 100.
Jacksonville, North/Northeast Florida: Locally heavy downpours expected in the afternoon and evening as rain and thunderstorms develop. Some stronger thunderstorms will be capable of producing gusty winds up to 50 mph which could cause minor wind damage. High near 92, with heat index as high as 101.
Daytona Beach to Stuart, East/Central Florida: June 11 will be hot and humid, with peak afternoon heat index values between 100 and 105. Scattered to numerous showers and storms will develop along and ahead of the east coast sea breeze this afternoon through early evening, with the greatest rain chances inland
West Palm Beach to Naples, South/Southwest Florida: Rain, heavy at times, is expected across South Florida. Some areas could see 2-3 inches of rain in a short period. Gusty winds and small hail are possible with afternoon storms. High near 83 in West Palm Beach. Temps could reach 88 in Naples, with a heat index near 100.
Fort Myers to Sarasota, West/Southwest Florida: The forecast calls for partly to mostly cloudy cloudy skies, with scattered to numerous showers and storms in the afternoon. Highs will top out in the upper 80's to lower 90s with heat indices hitting 100 to 107.
The Atlantic hurricane season runs from June 1 through Nov. 30.
Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said.
The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories.
The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center.
Systems currently being monitored by the National Hurricane Center include:
Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the tropical Atlantic basin.
To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA said.
Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated:
: for storms in the North Atlantic, central North Pacific, and eastern North Pacific.
: for storms in the Northwest Pacific.
: for storms in the South Pacific and Indian Ocean.
