Monday was the first day of the Atlantic hurricane season, which runs through November 30, and another named storm is brewing in the Gulf of Mexico.

Tropical Depression Three formed in the southern Gulf of Mexico on Monday afternoon, according to the National Hurricane Center.

The system is in the Bay of Campeche, in the far southern portion of the Gulf of Mexico, about 50 miles west-southwest of Campeche, Mexico.

The 2020 hurricane season is only two days old and is already an active one. Cristobal is now the third named storm of the season. It’s the earliest a third named storm has ever formed.

The main risk for this storm will continue to be rain. Ten to 20 inches of rain is possible across the Mexican states of Tabasco, Veracrus and Campeche. There could be isolated amounts of more than 2 feet of rain.

Tropical Depression Three is forecast to become a tropical storm Tuesday.

Once the system gets upgraded to a tropical storm, meaning winds of 39 mph or greater, it will be named Tropical Storm Cristobal.

“If this occurs before Friday, it will be the earliest in the year for a third named storm on record for the Atlantic basin,” CNN Meteorologist Brandon Miller says.

Nearly all weather entities – government agencies, institutions, and private companies – are forecasting for an above-average hurricane season for 2020.

Two tropical storms, Arthur and Bertha formed in May.

“Warmer than normal ocean temperatures in the Atlantic are part of the reason this season kicked off early,” Miller said. “It looks like another system is poised to form this week in the Gulf of Mexico, where ocean temperatures are running 1-2 degrees Fahrenheit above average.”

Tropical Depression Three was once Tropical Storm Amanda, which formed quickly across the eastern Pacific over the weekend but has since dissipated over Central America and southern Mexico.

“Even though this system originate from the remnants of Tropical Storm Amanda, it will get a new name, likely Cristobal, simply because it moved from the Pacific Ocean basin into the Atlantic Ocean basin, by way of Mexico,” said CNN Meteorologist Allison Chinchar.

In the short term, little movement is expected, as this system churns over southern Mexico, bringing heavy rain, flash flooding, and mudslides to the region. In the long term, this storm could track into the Gulf of Mexico by the weekend, becoming our third named Atlantic tropical storm of the season, Cristobal.

“Under the constant shadow of the coronavirus pandemic, this year’s hurricane season will be extraordinarily challenging especially if a high-impact event comes ashore. With already stretched resources and limited supplies, now is the time for people to prepare for the active season that is forecast,” said CNN Meteorologist Derek Van Dam.
