Text reads: The twin hurricanes in the Atlantic are moving away from the US, but the migrating birds are using the power of that wind to their advantage. The NEXRAD radar network (Doppler Radars In The US operated by the National Weather Service) showed about 492 million birds were in flight overnight and they were moving toward the southwest at about 30 mph just 1,200 feet above the ground. The low level winds are moving from the northeast to the southwest for most of the eastern part of the country. That is mostly due to the twin hurricanes in the Atlantic. Winds move counterclockwise around areas of low pressure. Since Hurricane Humberto is located northeast of Hurricane Imelda, those winds are out of the northeast and moving to the southwest in the migration zones. So once the birds take flight, they can glide in the right direction with lower effort than normal.
