Hurricane Irene

Hurricane Irene battered New York with heavy winds and driving rain on Sunday, shutting down the U.S. financial capital and most populous city, halting mass transit and causing massive power blackouts as it churned slowly northward along the eastern seaboard.

The hurricane may have passed and the sun may be coming out from behind the clouds, but people must still be careful before resuming normal activity. Federal Emergency Management Agency chief Craig Fugate pointed out the dangers that can still occur after a hurricane, the Associated Press reported.

Here are some things to keep in mind post-Hurricane Irene, according to the National Weather Service.

Branches can still fall down

Trees are weakened after a major storm due to all of the wind and water they have sustained. Therefore, branches can still fall down and cause injury to people passing by.

Stay away from flooded areas

Avoid the urge to wade through the murky waters that flood your streets. That water is potentially hiding fallen electrical wires and other dangerous objects.

Keep rooms ventilated to avoid carbon monoxide poisoning

North Carolina state health director Jeff Engel gave tips to avoid carbon monoxide poisoning and what to do.

If the electricity goes out during a hurricane, people often use gas generators for power, Engel said, Garner News reported. They might also use charcoal or gas grills for cooking and kerosene heaters for warmth. It is extremely important that people do not use these devices in enclosed areas where carbon monoxide - a poisonous gas - can cause death.
