25th Operational Weather Squadron Operational Weather Squadrons conduct weather operations in support of Total Force Army and Air Force operations covering a specified geographical region of the world. Weather officers and enlisted weather technicians operate around the clock to provide installation forecasts, aviation hazard decision aids, flight weather briefings, and weather advisories, watches and warnings. These regional weather 'hubs' are responsible for producing base or post forecasts, developing weather decision aids, briefing aircrews, and issuing weather advisories, watches and warnings for all units in their geographical area. Using automated observing systems located at most major installations and communicating with base or post weather flights, the squadron is able to 'forecast' the weather for the entire area of responsibility from one central location. The 25th Operational Weather Squadron, located at Davis-Monthan Air Force Base, Ariz., is responsible for producing and disseminating mission planning and execution weather analyses, forecasts, and briefings for Air Force, Army, Guard, Reserve, and combatant command forces operating at 82 installations/sites in a 11-state region of the western United States. The 25th OWS also produces 7,000 weather warning/advisories, 20,000 terminal aerodrome forecasts, 86,000 graphical aviation hazard products and 26,000 flight weather briefings per year. In addition to its operational mission, the 25th OWS serves as the training center for 20 percent of all new Air Force enlisted forecasters and weather officers. After completing an 8-month initial skills course, new weather apprentices report to the 25 OWS to complete a 15-month upgrade training process.
