The potential 1 million visitors expected in Charleston Monday should be warned: It may be cloudy during the eclipse. 

The latest update from the National Weather service predicts an 80 percent chance of cloud coverage over the Lowcountry at 2 p.m. The total eclipse for the area is to occur at 2:46 p.m.

The National Weather Service also says there is a chance of thunderstorms in Charleston tomorrow, but says that they likely would occur between 9 a.m. and 2 p.m. 

"Any thunderstorms that develop will be capable of producing heavy rain and cloud to ground lightning," the service explains.

They say that the best viewing scenario would be if the showers and thunderstorms occur "mainly in the early to mid morning hours with some potential partial clearing of clouds by early afternoon."

However, visibility would be poorest if "showers and thunderstorms continue to develop through the late morning, into the early afternoon, and clouds block viewing of the sky around eclipse time," accord to NWS.

Still, the service says that they have "very low confidence" in these early predictions, and many factors could affect the weather Monday. 

They will have a better idea after sunrise Monday morning.

Monday's high is 88 degrees in Charleston.

Those further northwest along the path of totality, the Midlands and Upstate, are expected to have better viewing conditions than the Lowcountry.
