Hartford, Conn. – Heavy rain is set to drench Connecticut from Thursday afternoon through Friday, bringing a statewide flood threat and possible road washouts in low-lying areas. A Flood Watch is in effect from 2 p.m. Thursday until 2 p.m. Friday, covering all counties.
According to the National Weather Service in Boston, most areas across Connecticut can expect 1 to 2 inches of rainfall, but localized totals of 3 to 4 inches are possible—especially in central and southern regions including New Haven, Waterbury, Danbury, and New London. These totals could lead to excessive runoff, flooding of rivers and streams, and standing water on roads.
Travel during peak rain hours may be hazardous, particularly on I-84, I-91, and Route 15, where ponding and flash flooding could reduce visibility and traction. Residents in flood-prone zones should avoid unnecessary travel, secure valuables in basements, and monitor alerts from local emergency management.
This rain system follows an already wet July, compounding the risk of flash flooding across urban corridors and low-lying farmland. Power outages are possible if storm drains back up or winds pick up during heavy bursts.
Flood alerts remain active through Friday afternoon, and additional advisories could be issued if rainfall intensifies overnight.
