Tropical Storm Michael formed near Mexico’s Yucatan Peninsula, but it is expected to threaten Florida’s Gulf Coast as a hurricane later this week, the National Hurricane Center said Sunday.

"It’s a tropical storm at the moment,” said Brian Fortier, a senior meteorologist at the Weather Channel. “Looks like it will become a hurricane in the next 24 hours and stay a low-grade hurricane before it comes onshore and moves northeast across Georgia, South Carolina and North Carolina.”

Fortier said the storm would be moving quickly, which could mitigate flooding in the Carolinas, where the floodwaters of Hurricane Florence have just receded.

“I don’t know how much rain they can take because of how saturated the ground is,” he said. “It’s going to be very concerning and create some localized flash flooding.”

The National Hurricane Center forecast that Michael would become a hurricane on Monday, only two days before it is expected to reach the Gulf Coast. The hurricane center warned residents the storm could bring dangerous surges, rainfall and winds.

Michael was moving north-northeast at about 3 mph Sunday but was expected to pick up speed over the next few days before striking the Gulf Coast on Wednesday. Minimum sustained winds were at about 50 mph and extended outward up to 205 miles, according to data collected by an Air Force Reserve reconnaissance aircraft. Those winds are expected to strengthen before Michael makes landfall.

In anticipation of the storm, Florida Gov. Rick Scott said he would be declaring a state of emergency in the Pensacola region and activate the state’s emergency operations center. He expected to be given a full briefing on Michael’s potential impact by federal, state and local emergency management, he said in a tweet.

Our state understands how serious tropical weather is and how devastating any hurricane or tropical storm can be. As we continue to monitor this storm’s path toward Florida, it is critically important that our communities have every available resource to keep everyone safe — Rick Scott (@FLGovScott) October 7, 2018

Sen. Bill Nelson, D-Florida., said Floridians would be following the storm’s path closely.

Floridians know firsthand how quickly storms can escalate. Residents on the Gulf Coast should keep an eye on this storm and heed any warnings from local officials. We're monitoring its path closely. https://t.co/XrTRvu8Zww — Senator Bill Nelson (@SenBillNelson) October 7, 2018

Before the storm hits the United States, Michael is expected to bring heavy rainfall and flash flooding to portions of Cuba and Mexico’s Yucatan Peninsula on Sunday and Monday. Tropical storm warnings are in effect in the two countries.
