What happened

The episode as NWS OKX wrote it up.

Tropical Storm Hanna impacted Southern Connecticut, making landfall near the Nassau/Suffolk County border around 10:35 pm on the 6th. Storm total rainfall ranged from 2.76 inches at Groton Airport to 6.45 inches at New Canaan. The highest sustained wind of 25 knots (29 mph) was reported in Bridgeport with the highest peak gust of 34 knots (39 mph) measured at Groton Airport. The lowest sea-level pressure was 996 mb. at Groton Airport. Coastal storm tides of 2 feet or less above astronomical tide levels were common. Near the coast, as well as inland, only scattered trees were reported down due to the wind, causing minor damage. No fatalities or injuries were attributed to the winds. All of the associated effects of Hanna resulted in an estimated $32,000 in property damage, and a minimal amount of crop damage. One person was killed due to flash flooding.
