The flood watch indicates favorable conditions for flooding, with a heightened risk of flash flooding in central, northern, and southern New Hampshire. Low-lying areas, including rivers and streams, are particularly vulnerable. Residents in Manchester have already experienced flooding, and additional rainfall could exacerbate these conditions. Thunderstorms and wind gusts may also pose localized hazards, such as downed branches or power outages. Travelers and residents in flood-prone areas should remain vigilant.
