While parts of the South may get a brief break in the extreme heat this week, the Pacific Northwest is sweltering and the National Weather Service warns record-breaking temperatures will expand into the Central U.S. by Friday.
Continued heat and drought conditions in Louisiana prompted Governor John Bel Edwards to declare a statewide emergency on Monday, as much of the South endures an ongoing heat wave.
The weather service has issued “a record number of excessive heat warnings for Louisiana” this summer, Edwards said. And heat-related emergency room visits have exceeded the annual average, according to the state’s health department.
While an emergency declaration is an administrative step that allows governments to direct resources to respond to emergencies, the Louisiana declaration also underscores the continued danger of heat baking parts of the nation.
Heat advisories and excessive heat warnings were in place in more than a dozen states Tuesday, stretching throughout the south and Pacific Northwest.
With more than a dozen Louisiana parishes under excessive heat advisories, Edwards urged residents to take precautions when outside and check on neighbors who might need assistance.
