The National Weather Service has issued heat warnings across the country, as the blazing sun heats up every corner of the United States. The oppressive, often humid heat has led city leaders to urge citizens to stay indoors and remain hydrated.
In an unusual move, a "no swimming" sign in Louisville, Ky., warns residents that the city's Waterfront Park fountain contains high levels of hydrogen. Park Development Corporation president David Karem says the tongue-in-cheek sign is an attempt to keep spirits high while keeping park-goers out of the fountain. Melissa Block talks with Karem to find out if the sign is working.
But at least one part of the country is keeping cool. The city of Forks, Wash., has the lowest forecast high temperature -- 65 degrees -- in the contiguous United States. Robert Siegel talks with Forks Mayor Nedra Reed.
