OUTLOOK: *** Moderate Threat *** Highly favorable conditions for pollen release. Temperatures, humidities, and winds are all favorable. If more pollen were available for release, we would have a Serious Threat (please note the reports below). Persons living in south-central and southeast TX may feel some ill effects from today's release. *** 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 the Junction area describes pollen levels that aren't high at this time and have yet to be high this season. Given the past and continuing dry weather, it appears that pollen production is, in general, comparatively less this year and is likely spotty in nature. We will continue to update you on the situation as we receive more information. *** TK
