What is the ‘dirty side’ of a hurricane?

TAMPA, Fla. (WFLA) — Our Max Defender 8 Meteorologists have often said the Tampa Bay area is on the “dirty side” of Hurricane Idalia, but what exactly does that mean?

Along the Gulf Coast of Florida, the “dirty side” of the hurricane is on the east side, Max Defender 8 Meteorologist Eric Stone said.

“Water is going to be pushed counter clockwise onto our coastlines from Sarasota all the way to Pinellas and even in Citrus County,” Stone said. “If you’re on the east side of a storm, typically you get a little bit more in the way of rain.”

Typically that’s where the isolated tornadoes will pop up, along with more rainfall, wind and storm surge, according to Stone.

When the rain bands over water come on shore, the friction of land causes spin up, which can lead to the isolated tornadoes, Stone said.
