Long Island’s weather network has expanded, with four monitoring stations added in the past two years designed to help with forecasting and decision making. The stations, in Stony Brook, Wantagh, Southold and East Hampton, are among 180 statewide that make up the New York State Mesonet, launched in 2014. (Also included is a close neighbor site in Queens.)
The Mesonet sites join other weather-data collection points on the Island and nearby, including area airports’ automated surface observing systems (ASOS). Here are the sites:

Among the sources not included are various buoys in the waters off Long Island, as well as the many volunteers who play a role.
Cooperative observers, including those in Riverhead and Syosset, gather daily weather basics for climate use, and trained spotters report on storm conditions in the moment, both after training by the weather service. The volunteer Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) shows reports from 39 Long Island locations the morning after a July 17, 2018, rain event, for example.
