Two disturbances in the tropics are worth watching for possible development that could send rain and cloud cover to Florida's Space Coast for the SLS launch on Aug. 29.
. "As a result, the primary weather concerns for a Monday morning attempt will be the Cumulus Cloud Rule, Surface Electric Fields Rule, and the Flight Through Precipitation constraint."
The SLS cannot launch through rain, and liftoff will be delayed if winds are between 29 and 39 knots above 132.5 feet. NASA Planetary Scientist Sarah Noble discusses everything you need to know about the upcoming Artemis l mission. Cumulus cloud cover within a 10 nautical mile range could also delay the launch, depending on the clouds' type, distance and height. The launch director will not allow the countdown to continue if the SLS flight path is within 3 nautical miles of a thunderstorm debris cloud.
