Tracking the Tropics: Can cold fronts become tropical systems?

TAMPA, Fla. (WFLA) — The tropics are slowing down as we get nearer to the finish of October and the climate begins to get cooler, however there’s nonetheless greater than a month left to go in the 2022 hurricane season.

The United States hasn’t had any landfalling tropical cyclone since Hurricane Ian hit Florida and, later, South Carolina.

Now, three weeks after Ian, most of the East Coast is coping with a blast of cooler air. Many Floridians woke up to temperatures in the 50s and 60s on Wednesday, because of a cold entrance that moved by Tuesday.

While the colder air could make it simpler for these residing on the East Coast and Gulf Coast to overlook about hurricane season, it’s essential to keep in mind that the season doesn’t finish till Nov. 30. A quiet basin proper now doesn’t imply we couldn’t see one other storm spin up off one in every of the cold fronts that make it down into the Gulf of Mexico or off the mid-Atlantic shoreline.

“Remnants of a polar front can become lines of convection and occasionally generate a tropical cyclone,” the National Weather Service mentioned. “In the Atlantic Ocean storms, this will occur early or late in the hurricane season in the Gulf of Mexico or Caribbean Sea.”

The present entrance impacting the United States doesn’t seem like favorable for any form of tropical group. But whereas it’s uncommon, that doesn’t imply future fronts are out of the query.

“We’ve seen fronts spin off tropical systems once they enter the Atlantic, but it does not look likely with this system,” WFLA Meteorologist Rebecca Barry mentioned. “Fronts more often steer any existing tropical systems away from the coast of the U.S.”

Barry added that we could not see one other hurricane-strength storm this season.

“Since 1950, we’ve had 53 hurricanes form after Oct. 1. That’s an average of .746 hurricanes per season after Oct. 1, so it’s entirely possible we may not see another hurricane this season,” she mentioned.
