Forecast Discussion
Space Launch Delta 45
A tight pressure gradient is being generated between the strong high-pressure area anchored over the north Atlantic and Tropical Storm Eta over Central America. This creates breezy, onshore flow along the Space Coast, with rain shower chances increasing over time. The primary weather concern for a Thursday evening launch attempt is Liftoff Winds and the Cumulus Cloud Rule associated with the showers. On Friday, Tropical Storm Eta will likely move northward, adding moisture over the Spaceport while strengthening our winds. The primary weather concerns remain Liftoff Winds, and the Cumulus Cloud Rule, with the addition of the Thick Cloud Layer Rule
