Just one week after Tropical Storm Ophelia caused flooding across Rye, the City is warning of flash flooding risk Friday evening into Saturday. Localized flooding could be significant  “posing an elevated threat to life”.

The following notice was issued by the City just after 6:30pm Friday evening:

Widespread 1 to 2” of rainfall is likely, with localized 3 to 4” possible across the Flood Watch area. Locally 1 to 2“/hr rainfall rates possible across this area during a 6-9 hr period between 4am and 2pm Saturday.

If and where the heaviest rainfall rates and amounts occur, flooding could be locally significant, causing disruption to transportation, flooding basements, first floors of residences and businesses, and underground infrastructure, and posing an elevated threat to life.

Those in the Flood Watch should prepare for the locally significant flood impacts.
