PHILADELPHIA — With temperatures forecast to head deep into the 90s for the next several days and with a heat advisory in effect through Sunday — when it might hit 100 — Philadelphia has declared its first “heat health emergency” of the season.
The Public Health Department announced the emergency declaration would be in effect from noon to 8 p.m. Thursday but could be extended if conditions warrant during what might become the region’s longest heat wave in nine years.
By 9 a.m. Thursday the heat index already had crept up to 95 on what the National Weather Service says is going to be the most-oppressive day of the heat wave so far. And it might be one- or two-upped during the weekend.
