HUNTSVILLE, Ala. (WHNT) - If you or a loved one will be flying today or tomorrow, be aware the winter weather around the U.S. may impact you. Some arriving flights at Huntsville International Airport have been delayed or cancelled throughout the evening and into the morning.
Some flights out of Houston, Dallas-Fort Worth and Atlanta are cancelled. That impacts flights into Huntsville.
Runways there were more soggy than anything Monday afternoon, but operations crews at the airport will be checking throughout the evening to ensure that doesn't freeze.
Wes Williams, Huntsville International Airport's Operations Manager, showed us a Bowmonk decelerometer his teams use to test runways for slick conditions.
"We reach a speed of approximately 40 miles an hour [in our own vehicles out on the runway] and we aggressively brake using our vehicle. And this machine uses a coefficient of friction to determine how well or how poorly an aircraft brakes are going to perform on our runways," he said.
The machine is secure inside the car so it doesn't go flying at an abrupt stop.
"[The information we get back] is conveyed directly to air traffic control and our pilots," said Williams.
The Madison County Shuttle, a company that provides rides to Nashville's airport and back, halted its service for the day due to dangerous driving conditions in Tennessee.
"It was heavy ice. The driver wasn't comfortable going over 35 miles an hour [on the interstate]," said owner and founder Roger Nunamann.
He said he would decide around 1:45 a.m. Tuesday whether it was safe to operate for their usual 2:45 a.m. run to Nashville.
