mid-july pdpt map

Areas shaded dark green have seen more than double their normal precipitation so far this July.

A large portion of the Northeast was wetter than normal during the first two weeks of July, receiving 100% to more than 200% of normal rainfall. The precipitation frequently fell in quick, heavy bursts, resulting in flash flooding in some areas. Conversely, portions of Maine, central New Jersey, and eastern West Virginia received below-normal rainfall, with parts of coastal Maine seeing less than half their normal precipitation so far this July. Twenty-three of the region’s 35 major climate sites saw above-normal rainfall, with 14 of them ranking this July 1-15 period among their top 20 wettest. However, Portland, ME, had its 10th driest first half of July on record.
