On Wednesday, hundreds of thousands of residents in the Northeast prepared for a long, cold night.

Many of the same areas hit by Superstorm Sandy are now experiencing a nor'easter. 
 
"While this storm is not as dangerous as Sandy was, New Yorkers should still take safety precautions today and tonight," New York Mayor Michael Bloomberg told reporters Wednesday.

According to CNN forecasters, there may be “gusts of up to 60 mph in shore towns and cities across New York and New Jersey, bringing 2- to 4-foot storm surges.”
      
Those without shelter are dealing with potentially deadly conditions as freezing temperatures usher in snow.

How much can these people endure? HLN’s Dr. Drew and his special guests cover the story.

AS MENTIONED ON TV:

5 must-haves to prepare for disaster (as mentioned by former Navy SEAL Cade Courtley, author of "A Navy SEAL's Secrets to Surviving Any Disaster")

1. At least one gallon of water per person, per day. Water is mandatory.  Humans can survive without food for 72 hours -- even a week or more -- but liquids are crucial

2. $100 in small bills. Assume ATMs not functioning and merchants not having change for large bills

3. Prescription medication to get you through at least two or three days

4. Sealable plastic bag w/ photo copy of passport or license and contact numbers of family, friends and doctor.  Don't rely on stored contact numbers in your cell. You may not be able to charge it

5. Flashlight with extra batteries or glow sticks
