BATON ROUGE – Periods of heavy rain are expected into Saturday morning as short-lived Tropical Storm Olga merges with a cold front and move over Louisiana.

When the storm systems merge later Friday the weather system will become a post-tropical low with gale force winds.

Heavy rainfall could lead to flash flooding, the National Weather Service warned again Friday afternoon. A storm total 1-3 inches of rain is expected, with isolated higher amounts possible. A flash flood watch was issued until 1 p.m. Saturday.

While the threat for severe weather will be low, a long duration soak and a few downpours could lead to street and poor drainage flooding, Dr. Josh Eachus, WBRZ’s Chief Meteorologist, reported on his blog Friday.
