More rain coming later in evening

The chance of rain will remain low throughout the evening until 8 p.m., according to the National Weather Service. Overnight, more rain is expected.

A flood advisory for Clermont, Butler, Warren and Hamilton counties in Ohio has expired. The heaviest rainfall has exited the area but flooding may still occur, according to the National Weather Service.

The severe storm Monday afternoon prompted tornado warnings in Clermont, Campbell and Pendleton counties and at one point almost 60,000 people in the region were without power.

Reports of downed trees and power lines and lighting strikes were still coming in after the worst of the storm appeared to pass through just before 3 p.m.

Lightning struck a home on Grandview Road in Alexandria and put a hole in the roof around 2:30 p.m.

The threat of severe weather lingers, though. The region is under a severe thunderstorm watch until 8 p.m., when the Home Run Derby is scheduled to start.

There has only been one Home Run Derby rained out – in 1988 in Cincinnati. Last year, the Home Run Derby in Minneapolis was delayed for rain.

Though there was never a tornado warning issued for Hamilton County, the county's Emergency Management Agency sounded sirens around All-Star Game venues at 12:30 p.m. to get crowds to take cover.

Three sirens around the Great American Ballpark sounded to encourage visitors to seek shelter. The sirens do not usually sound for thunderstorms.

The Summer Celebration at the Covington Landing was closed at 12:51 p.m. due to the storm. Cov200, which is hosting the event, announced that the celebration would re-open once the storm passes.

A very wet weekend

The Ohio River is creeping upward in depth, and toward its 40-foot action stage. As of 3 p.m., the river was observed at more than 38 feet, according to the weather service. Flood stage is 52 feet, according to the National Weather Service.

The storms rolled through early Sunday morning, providing heavy rain, cracks of thunder and flashes of lightning. Continued rainfall would figure to threaten Major League Baseball All-Star Game festivities at Great American Ball Park.

The SiriusXM Futures Game started on schedule at 3 p.m. The All-Star Legends and Celebrities Game will follow.

Rain also caused issues on some roadways Sunday morning as trees have been uprooted, presumably as a result of sodden ground. An unconfirmed mudslide report was also broadcast via Cincinnati police emergency communications at about 7:30 a.m.
