Tropical Depression 10 forms in Gulf of Mexico. It could hit Florida as Hurricane Idalia

The National Hurricane Center is monitoring a tropical depression that formed Saturday in the Gulf of Mexico. Its projected path has it making landfall on the west coast of Florida or the Florida Panhandle next week.

Tropical Depression Ten is expected to become the ninth named storm in the Atlantic hurricane season. Its name would be Idalia.

Forecasters are advising Florida residents to monitor the storm's development. Current forecasts have it making landfall Tuesday night or Wednesday morning. On Saturday, Gov. Ron DeSantis issued a state of emergency for 33 counties ahead of the storm.

At 8 p.m., the center of Tropical Depression Ten was located off the coast of Cancun. The depression is nearly stationary, and little overall movement is expected through Sunday.

A slow, generally northward motion is expected to begin on Monday. On the forecast track, the center will move into the southeastern Gulf of Mexico by Monday.

Gradual strengthening is forecast during the next 48 hours, and the system is likely to become a tropical storm on Sunday. The system could then become a hurricane over the eastern Gulf of Mexico by Tuesday.

When maximum sustained winds reach 39 mph, it will become a tropical storm.

"Rapid development and strengthening could take place in the eastern Gulf of Mexico where the feature transitions from a tropical depression to a Category 1 hurricane in the span of 24 hours," said Adam Douty, AccuWeather senior meteorologist.

Key messages from the Hurricane Center: What you need to know about Tropical Depression Ten

  1. Heavy rainfall from Tropical Depression 10 is expected across the Yucatan Peninsula and western Cuba. The heavy rainfall may produce areas of flash and urban flooding, as well as landslides, across western Cuba. The depression is forecast to become a tropical storm by Sunday, and tropical storm conditions are expected over portions of the Yucatan Peninsula where a tropical storm warning is in effect. Tropical storm conditions are possible over western Cuba within the tropical storm watch area.

  2. The depression is forecast to strengthen over the next few days and could become a hurricane in the Gulf of Mexico, bringing a potential of dangerous storm surge, heavy rainfall and strong winds to portions of the west coast of Florida and the Florida Panhandle by the middle of next week. Heavy rainfall is also likely to spread into portions of the Southeast U.S. by mid- to late next week. Although it is too soon to specify the exact location and magnitude of these impacts, residents in these areas should monitor updates to the forecast of this system and ensure they have a hurricane plan in place.
