Epi Week #26 - 2017 General Statements
Collections were back up again this past week after a drop for Epi Week 25. We also had our first WNV-positive mosquito pools, in opposite ends of the state (Berkshire and Suffolk Counties). This is a little earlier than is typical but no cause for alarm. Some MCDs are reporting seeing a larger than usual mix of species this season; it will be interesting to see if this holds up as we hit mid-summer.
Weather
Most of the state had moderate precipitation this past week, with pockets of rain exceeding 1.75” in several areas including Franklin/Hampshire County, central Worcester and central Middlesex Counties, and northern Essex County
As this report goes to press (July 7), the state is in the middle of yet another storm event, with a Canadian airmass the big variable that will determine whether things carry into Saturday or just clear up. Expect downpours to hit some areas at the end of Epi Week 27. Looking into Epi Week 28, expect slightly below normal precipitation and above-average temperatures.
