National Weather Service officials said remnants of Tropical Storm Beryl are expected to track across the Lower Great Lakes region Tuesday night into Wednesday, possibly causing flooding and strong wind gusts.

A flood watch is in effect until Wednesday afternoon when excessive rainfall may cause flooding to rivers, creeks and streams as well as low-lying areas, officials warn.

There is a chance of thunderstorms Tuesday in portions of north central and northeast Illinois, and northwest Indiana. Also, officials expect hazardous swimming conditions in Lake Michigan beaches starting Tuesday night. The heavy rainfall is expected along and southeast of Interstate 55, officials said.

The remnants of Beryl are expected to move northeast into the region Wednesday. Officials said tropical moisture associated with the storm was expected to create bands of heavy rainfall into early Wednesday.

By Tuesday afternoon city officials issued a beach hazard alert, warning of waves 4 to 7 feet high at Lake Michigan beaches.

Beryl, which made landfall early Monday as a Category 1 hurricane, has been blamed for at least seven U.S. deaths — one in Louisiana and six in Texas — and at least 11 in the Caribbean. At midday Tuesday, it was a post-tropical cyclone centered over Arkansas and was forecast to bring heavy rains and possible flooding to a swath extending to the Great Lakes and Canada.

Temperatures are expected to remain in the high 70s Tuesday, with a 60% to 100% chance of showers.
