This was the ninth day in a row with measurable rain. In total, 5.93" fell, with more than half (3.34") falling on the 12th and 13th.
Today's high/low of 77°/72° was the tenth time this summer temperatures were stuck in the 70s for the entire day - the most of any year (a record that still stands).
After receiving just 0.08" of rain in the first two-and-a-half weeks of the month, a weakening hurricane to the southeast dumped nearly four inches, with most of it falling between 2 PM and midnight. It was also a chilly day, with temperatures falling into the upper 50s during the afternoon. This was the City's biggest rainstorm since Sept. 7-8, 1934, when a category 1 hurricane made landfall on Long Island and dumped 5.48" of rain in Central Park.
2.18" of rain fell during the morning, most of it between 9-11 AM, as the remnants of Hurricane Ivan moved through. Ivan's rainfall was much heavier in Pennsylvania and upstate New York.
A squall line rolled through between 7:30-8:30 PM and dumped 1.06" of rain in a 30-minute period.
The remnants of Hurricane Florence, which brought disastrous flooding to southeastern North Carolina a few days earlier, synched-up with a cold front and brought heavy rain during the afternoon (12:30-4:30), producing 1.16". When the rain began, the dew point was at a sticky 74°. This rain came eight days after the remnants from Hurricane Gordon brought 1.38" of rain (but it fell over the course of nearly 24 hours).
