As Hurricane Sandy lashed Cuba Thursday, weather forecasters predicted its effects could hit the DC/Baltimore metro region by Sunday. Power companies said they were gearing up for possible outages.

The Category 2 hurricane has already killed 21 throughout the Caribbean, according to NPR, and it could merge with a strong cold front in this area to create what The Washington Post's Jason Samenow called a potential "powerhouse."

Although the storm's path has not yet been confirmed, most predictions say it will travel up the southeast coast and make landfall in the mid-Atlantic.

The Post's Capital Weather Gang is suggesting the storm may slam the mid-Atlantic starting Sunday.

Baltimore Gas and Electric Company (BGE) says the company hs preparing for the storm.

“BGE has begun the process of pre-mobilizing its field and contractor crews, as well as support staff, well in advance of the potential impact of Hurricane Sandy,” Jeannette M. Mills, vice president and chief customer officer for BGE, said in a statement Thursday.

“Additionally, BGE is proactively coordinating and securing out-of-state mutual assistance crews to ensure they are in place in advance of the storm.”

A spokeswoman also suggested residents prepare with the tips below.

• Stay informed – Stay aware of changing weather conditions and plan ahead. Have a battery-powered radio with a weather band so you can hear emergency information when the power is out.
• Make a plan – Discuss and document an emergency plan with those in your care. Develop a family emergency plan that includes alternative arrangements should the need arise to leave your home. Make provisions for special needs of any family member such as the elderly, handicapped, medically affected or infants. If you are dependent on electric-powered medical equipment, you are encouraged to seek alternate arrangements  in the event that your electric service is interrupted.
• Make a list of emergency phone numbers and keep a personal telephone book and one corded phone or a cell phone on hand.
• Build an emergency kit – Keep enough emergency supplies on hand for you and those in your care. Remember supplies for children, those with special needs and pets. Keep the following items readily available.
  • Flashlights – not candles
  • Fresh batteries
  • Battery-operated clock radio
  • Corded telephone
  • Fully charged cell phone
  • Non-perishable foods
  • Water – one gallon of water per person per day for at least three days for drinking and sanitation
  • First aid kit
  • Local maps
  • Blankets

Residents are also urged to stay away from power lines during the storm.
