Eastern Range Operations Forecast Op Number: F9695

Issued: 2 July 02 / 1030 EDT Valid: 3 July 02 / 0247 EDT Note: Forecasts

Vehicle/Payload: Delta II / Contour

Location: SLC 17A

Launch Weather Officer: Joel Tumbiolo

Synoptic Discussion:

Low pressure center located east of the area will be the main driver for

weather conditions during the launch countdown.  Showers and thunderstorms

will rotate in a counterclockwise direction around this low pressure center,

with activity affecting the Cape coming from the W through N.   Wind field

from the surface through 30 KFT will be less than 10 KTS.  Main concern

initially will be local conditions at the time of MST Rollback.  Afterwards,

launch window concerns will be cloud cover and any showers and thunderstorms

still in the vicinity.
