These tips can help you survive the bitter cold

Opening day for the Cubs and White Sox is just 81 days away. Try to remember that when you step out into today's bitter cold.

Temperatures today probably won't get as high as zero, and wind chills could drop to 30 below. High temperatures on Friday will be in the single digits.

The bone-chilling cold comes near the end of a week that's already been a character-builder for the suburbs. In addition to cold and wind, the region endured a record ninth consecutive day of measurable snowfall on Wednesday, according to the National Weather Service.

So, are you sick of winter yet?

Of course, weather this cold isn't just a nuisance, it's downright dangerous. Here are a few tips on how to stay safe and comfortable during a brutal cold snap.

And try not to despair - you'll be digging out those Thome and Soriano jerseys before you know it.

Stay safe in and out

These tips come from the Centers for Disease Control and Prevention. To download a complete cold-safety guide, go to emergency.cdc.gov/disasters/winter/.

• During a cold snap, make sure you're well stocked with clean water and food that needs no cooking or refrigeration.

• When home, leave water taps slightly open to keep pipes from freezing. Open doors under sinks to allow warm air to circulate around pipes.

• Avoid alcoholic or caffeinated drinks, which cause you to lose heat more quickly.

• Dress in layers when going out. Wool, silk or polypropylene inner layers hold more body heat than cotton.

• Avoid overexertion while outdoors, especially when shoveling snow.

Cold and your car

Beth Mosher, spokeswoman for the AAA Chicago Motor Club's Aurora office, said the agency was bombarded Wednesday with calls about dead batteries and vehicle stalls. She offered these tips for keeping you and your car going. More are available at aaa.com.

• Always keep at least half a tank of gas in your car. "It prevents the fuel line from freezing, and it will ensure that you don't run out of gas while on the road," Mosher said.

• If you do get stranded, stay with your car. Emergency crews won't be able to find you otherwise.

• Before hitting the road, clear all snow off your car so it doesn't blow onto your windshield while driving.

• If possible, park in a garage. If you can't, put a tarp over the hood to protect the car overnight.

• Check your battery strength. Faulty batteries are the No. 1 cause of starting problems.

Protecting pets

Extreme cold can be harmful to dogs and cats as well as people. Cyndi Faulkner, owner of Central Bark Doggy Day Care in Gurnee, said taking a few simple precautions can keep our four-legged friends safe. (More are available at centralbarkusa.com.)

• A dog's ears are particularly susceptible to frostbite. If you suspect frostbite, warm your dog by bringing him inside and covering him in warm blankets. Do not rub his ears.

• Water is vital to your pet's health. Make sure your dog or cat has unfrozen water available. (Many pet stores sell heated water dishes.)

• Rock salt can irritate dogs' paws. Consider using a pet-friendly alternative, or buy boots or paw wax for him.

• Cold weather can exacerbate arthritis in elderly or overweight dogs. Call your veterinarian if your dog is having difficulty walking or moving.
