OUTLOOK: *** Low to Moderate Threat *** Generally unfavorable conditions for pollen release. Afternoon temperatures will be in the favorable range.....but humidities will be on the rise as the day progresses. Pollen cones are beginning to release any pollen in the Austin area. Any transport will carry pollen to West Texas. Overall a Low Risk of pollen transport to major urban areas. TK, EL
