Northeast Drought Early Warning System

Conditions for the week of September 5 – 11

After the first 6 days of the period saw little or no precipitation across most of New England and degradation looked probable, Day 7 brought widespread light to moderate rains (1-2.5 inches) to the drought and abnormally dry areas of upstate New York, Vermont, New Hampshire, and coastal Maine. Decent rains (1-2 inches) also fell on far western New York (near Buffalo) during Day 6. As a result, short-term deficits were reduced enough to allow for some 1-category improvements in western New York, the southern sections of the drought area in upstate NY, Vermont, and New Hampshire, and along coastal Maine, with the latter area’s recently introduced D2 improved to D1, and the former D1 area shrunk. USGS 1- and 7-day averaged stream flows responded to the rains, rising into the near normal category except for far northern locations that received lower amounts and stayed in the 10th (much below) to 24th (below normal) percentile. In contrast, little or no rain was reported in far eastern Maine (Aroostook county) where 30- and 60-day precipitation was below normal along with low 7-day averaged stream flows, thus the two separate D0 areas in eastern Maine were merged. The D0 in eastern Massachusetts remained unchanged as enough rain fell (~1 inch) to prevent deterioration, but not enough for D0 removal with shortages remaining at 30-, 60-, and 90-days.
