They're watching the weather closely at NHMS
But forecasters say the rain should end Sunday morning, which should give the speedway's elaborate road-drying system time to dry the oval track for Sunday's Sylvania 300 NASCAR Sprint Cup Series race, which is scheduled for 2 p.m.
Speedway officials monitor storms in the track's weather center, which is part of the NHMS Command Center in the offices atop the grandstand. The command center is a large room where track security planning and management takes place. It includes sections for local and New Hampshire State Police, the Department of Homeland Security, the state Bureau of Emergency Management, the FBI, and track security.
If it's raining at race time, the race will be postponed, either to later Sunday or Monday.
When rain falls before a race, track crews can usually get the road dry quickly, he said, using the track's seven jet dryers, which are jet engines mounted on the back of trucks.
"We usually look at a two-hour window in terms of the time it takes to dry the track," he said.
According to the weather service, rain from an incoming weather system should end by late Sunday morning.
"We have no reason at this point to believe the race will be delayed (by rain)," he said Friday.
