The U.S. East Coast, which has been battered by the most devastating storm to hit the region in decades, is slowly recovering from the impact. The Port Authority of New York and New Jersey said John F. Kennedy International Airport in New York and Newark International Airport in New Jersey would open at 7 a.m. Wednesday with limited services.

Both the airports, along with many other airports on the U.S. East Coast, were closed Monday and Tuesday due to Superstorm Sandy. An estimated 15,000 fliers were stranded across the country.  

According to an Associated Press report, the Port Authority said that some carrier flights without passengers would land at JFK Airport from Tuesday night to start operations Wednesday morning.

The authorities said the services will be limited at first. They did not clarify the number of flights or destinations.

LaGuardia Airport at New York will remain closed Wednesday.

Regional utility service providers have begun assessing the damage and working toward restoring power and public transportation. An estimated 7.2 million are still without power in the country.

With most of the tunnels and subway stations submerged, officials believe that it will take a minimum of two to three days to normalize the power supply. Resuming subway transportation operations will take a few more days.

The death toll in New York has reached 18, bringing the total loss of life in the country due to Superstorm Sandy to 48. Most of the deaths were caused by falling trees.

Meanwhile, a weakened Sandy is heading toward Canada. President Barack Obama has warned that storm is not over, referring to the storm's damage, the danger from downed power lines and damaged trees, as well as flooding. 

"This storm is not yet over," Obama said during his visit to the headquarters of the American Red Cross in Washington, D.C., to review rescue and recovery operations in the aftermath of the mega-storm that caused unprecedented damage to the region, the AP reported.
