Joel Tumbiolo, U.S. Air Force Delta II Launch Weather Officer, 45th Weather Squadron, of Cape Canaveral Air Force Station noted that there is a 40% chance that weather issues will delay the launch.
"The clouds are the concern," he
told the LRR group.Typically, the sea breeze on Florida's east coast develops around noontime from June through September, and that can create clouds over land.There's a "Cumulus Cloud Rule" which states that if a cumulus cloud is a certain height, it must be a certain distance from the launch vehicle.There are no issues with winds, which are expected to be light.Tumbiolo
forecast during the GLAST pre-launch press conference held at 1 p.m. on June 9 at Kennedy Space Center
, carried live on NASA-TV.
