Thunderstorm wind is the clearest hazard at Weir Farm, with 128 recorded events in Connecticut — the single highest incident category by a wide margin. Those storms frequently arrive fast in the warmer months, and with 59 flash flood events also on record, rain-heavy afternoons can turn the park's low-lying areas and access roads into a serious problem within minutes.
Before heading out, download a radar app like RadarScope or MyRadar so you can watch incoming cells in real time rather than relying on general forecasts. Park your RV or pitch your tent away from large trees and any natural drainage channels that could funnel runoff quickly. If you're day-tripping, keep a dry bag with your essentials in the car so a sudden downpour doesn't cut your visit short with wet gear and no backup plan.
