OUTLOOK: *** Low Threat *** Unfavorable conditions for pollen release today and Saturday. Temperatures may reach the favorable range..... but moisture levels are far too high for pollen release. Similar or worse conditions expected Saturday. Rain is either forecasted or already occurring over much of the Plateau today and Saturday. Very little to no release expected either day. *** Recent reports from the Edward's Plateau are mixed with regard to pollen availability. According to Dr. Jack Kent in Austin, there is little to no pollen on the trees in the area. Yet, he reports allergic symptoms, indicating some pollen is in the air. Information from Bill Durbon in Junction describes relatively low pollen levels at this time, with no profuse pollination to report. Trees have appeared ready to pop for several weeks but have yet to do so. *** Given the past and continuing dry weather, it appears that pollen production is, in general, comparatively less this year and likely spotty in nature. We will continue to update you on the situation as we receive more information. *** TK
