My recommendation is choosing a PWS on Fire Island. Had the team do a quick review and looks like you have quite a few options very close-by to your controller.
My general thoughts about WI Plus…
In regards to WI Plus, there are two options.
Interpolated weather data that you don’t have to worry about stations going down or not reporting precipitation which takes the burden off the homeowner of making sure they have an accurate reporting station. Interpolated data is great but won’t be exactly the measured amount that a PWS would give you near the house.
The ability to choose from over 250,000 PWS stations (Gen 1/2 has about 40,000 PWS stations). We are also wrapping up a WI plus feature that will self “heal” a chosen station, always making sure you are using one that is online, automatically choosing the next closest station.
I usually recommend choosing a PWS station if you have one that you feel that it is reporting accurate data. A chosen station will always be more accurate (and more timely) than interpolated data.
In an upcoming release we will default to a chosen PWS station and will also have weather station “self” healing as described above. Stay tuned.
As far as precipitation forecasting I can’t help much there. We use a leading edge weather service to provide that and it is an amalgamation of radar, national stations, satellites, and weather models.
Hope this helps.
