The remnants of Hurricane Isaias could bring heavy rain, gusty winds and the chance for brief tornadoes to Indiana this weekend, with the primary window for impacts expected Saturday night into Sunday morning, National Weather Service forecaster Jason Puma said.

The storm is expected to make landfall near the Alabama-Florida border before moving north through Alabama and the Tennessee River Valley toward Kentucky and southern Indiana.

Puma said the storm’s track depends in part on the larger weather pattern, including a high-pressure system positioned to the east and southerly winds that could help steer the system north toward Indiana.

“Those southerly winds are in place, allowing that system to move north across Indiana,” Puma said.

The remnants could bring several types of weather to the state, even after the hurricane loses its tropical characteristics.

“When we do get impact — and we do get impact from hurricane remnants from time to time — they tend to be generally in the form of some heavy rainfall,” Puma said.

While heavy rain is the primary concern, Puma said the remnants can also produce isolated severe weather.

“We can get some brief spin-up tornadoes from time to time and maybe some gusty winds in the neighborhood of 40 to 50 miles an hour,” he said.

The timing of the system remains important, with Saturday night into Sunday morning expected to be the primary window for potential impacts in Indiana.

Puma said the storm’s eventual path will depend on how the weather pattern develops, but the current setup could allow its remnants to move north into the state.
