PHILADELPHIA (WPVI) -- Philadelphians should prepare for dangerous temps as the region sees the coldest day in nearly two years on Tuesday.
Not only will temperatures be in the single digits, but the wind chills will also be below zero for the next several nights, according to Action News meteorologists.

There are cold weather alerts throughout the region until Wednesday.
The high on Tuesday is expected to be just 19 degrees. A storm to the south could also graze the coast with evening snow showers.
That means another very cold night in the single digits is expected.
Wednesday will also be another brutally cold morning, with temps in the single digits and wind chills below zero again.
We won't start to warm up again until Thursday, which is expected to be in the low 30s.

This means ice is on the minds of commuters Tuesday morning.
PennDOT crews were out making the rounds during and after Sunday's snowstorm, so a lot of the roads are clear for today. However, the threat of ice remains and you can't always see it.
The Office of Homeless Services in Philadelphia has declared a Code Blue as of Sunday at 3 p.m. ahead of the deep freeze.
That means, during this time, as many as 19 warming centers are available with extra seating to boost capacity.
With the Code Blue in effect, the city's outreach teams are increasing their presence on the streets to encourage people living outdoors to head to one of the warming centers. Transportation will be provided.
Find a warming center location
Anyone who needs a warm indoor place to stay may visit a warming center, where food is also available.
They may also call the Department of Behavioral Health and Intellectual Disability's Homeless Street Outreach Team at (215) 232-1984 to get a ride to one.
Dozens of schools are starting late or on a modified schedule Tuesday due to the frigid temps.

Don't forget about your pet amid freezing temps.
Jackets can help, especially for smaller, short-haired dogs.
Booties can also help protect your dog's feet from frostbite and from chemicals used on streets and sidewalks to melt snow.
"It can be really hazardous to their health because they're always licking their paws, so what I always do if I'm walking my dog and I don't know what's on the sidewalk, I will take him in and I'll wipe his paws down really, really good so you get all those chemicals off your animal's paws," said Best Friends Animal Society CEO Julie Castle.
When the temperature begins to drop, you may need to take action to protect your pipes from freezing.
Water expands when it freezes, so when water in your home pipes start to expand, it has nowhere else to go and can cause your pipes to burst.

The cold snap also means many will crank up the heat in their home -- if it's working.

Action News spoke to That HVAC Guy, who deals in emergency services, heating and cooling, and plumbing services.
"Anytime the temperature has a major change, that's when systems like to go," said Jordan Fleming with That HVAC Guy.
Experts say to try some preventative maintenance as well. Having your system checked and filters changed helps to prevent those more expensive HVAC visits.
