Bismarck's National Weather Service helps track Hurricane Irma with balloons

BISMARCK, N.D. - Hurricane Irma is now a Category Five storm, and weather experts are warning people along the East Coast to get ready and be prepared to evacuate.

Bismarck's National Weather Service is helping track the path with balloons.

The NWS is releasing balloons every six hours to help track Hurricane Irma's path and intensity.

The National Weather Service says releasing these balloons is important because it gives them a direct observation that they can't get anywhere else.

"These extra balloon launches across the country are going to help, especially with the models. It will help determine where this hurricane's going to go," said Zach Hargrove.

The next balloon that's going to be released is at midnight.
