There is more drought improvement to report, but the same for next week is unlikely. Widespread drought conditions remain, but severe drought (D2) and extreme drought (D3) have been downgraded to moderate drought (D1) in approximately 50% of the southeastern area of the state which has experienced the worst dry conditions. There is no rain forecast through the weekend or early next week and above normal temperatures in the 60s are expected, with southern parts of New Hampshire potentially seeing temperatures in the low 70s on Saturday. Outlooks for mid-November indicate precipitation received is likely to be normal to slightly above normal. Since last week, the U.S. Monthly Drought Outlook has been released and indicates it is unlikely there will be more drought improvement by the end of the month.
ATTN: While the growing season is over, the warmer temperatures over the next few days are likely to result in an increase of outdoor water use as people head outdoors to wash cars, power wash, and tie up other fall cleanup chores. Please keep the public reminded of outdoor water use restrictions, as well as indoor water saving tips. To date, 165 community water systems serving 345,000 people and eight municipalities with a total population of 66,000 have water use restrictions in place (Restriction List and Map).
New Monthly Groundwater Update! While the majority of the wells in the New Hampshire Geological Survey’s monitoring network are experiencing below normal to low groundwater levels, recent precipitation has raised groundwater levels in many of the wells in the northern portion of the state from low to normal. With slightly below average precipitation in the central and southeast portions of the state, falling or below normal to low groundwater levels continue. For more information, see the New Hampshire Groundwater Level Monitoring Report for October 2020. Reports are released monthly.
