PHILADELPHIA (WPVI) --Sunday's miserably, hot weather did not cool the fire of Hilary Clinton supporters in Philadelphia.
For one delegate we spoke with from Texas, today's heat was no big deal.
"I live for this kind of weather. It's my favorite time of the year," said Pam Durham, Texas delegate.
Indeed, but the mayor reminded everyone Philadelphia's 1-2 punch of heat and humidity can be dangerous.
"The city already had four heat-related deaths this year. I urge residents to drink water frequently, check on their neighbors, limit time outdoors as much as possible, and keep their windows open if they do not have air conditioning," said Mayor Jim Kenny.
The sun-baked pavement blistering hot, while Rocky didn't break a sweat, those lining up for pictures relished the shade and bottles of water.
"Definitely drink lots of water, cool clothes, trying to stay in the shade," said Erin Maedeker of Columbus, Ohio.
At the pop-up park across the street, some made their own shade, found water and other ways to cool off.
For many, however, the heat isn't just a nuisance, it's dangerous.
The Philadelphia Corporation for Aging (PCA) has activated its Heatline again.
The line will remain open for at least the next few days.
Nurses and experts are on hand to answer questions and assist anyone who needs help coping with the extreme heat and humidity.
"We haven't had really hot days like that this year or even in the last couple years. That becomes very dangerous for people to be able acclimate to that kind of temperature," said Chris Gallagher, Philadelphia Corporation for Aging.
Heatline hours are as follows:
Sat., July 23, from 11 a.m. to midnight
Sun., July 24, from 8:30 a.m. to midnight
Mon., July, 25, from 8:30 a.m. to 6 p.m.
The number to call is 215-765-9040.
If you see someone homeless suffering in the heat, call the 24-hour Project Homeless Coordination Center Hotline at 215-232-1984.
