A slow-moving coastal storm will make its closest approach to Connecticut overnight, bringing periods of heavy rain, gusty winds and a potential for coastal flooding through Sunday and into Monday, meteorologists said.
Timing and main hazards
The period of greatest concern runs from late Saturday evening into Sunday morning. Forecasters warned the storm will produce sustained showers, pockets of heavier rainfall and wind gusts of 30–40 mph, strongest early Sunday. Temperatures will be unseasonably cool, running roughly 10 degrees below normal for the region.
Coastal flooding and tides
Authorities are monitoring the potential for coastal flooding tied to the combination of onshore winds and high tides. The highest tide cycle of concern is between about 10 p.m. and midnight Saturday night, with another vulnerable high-tide period Sunday morning.

Impacts and advice
This system has potential to disrupt travel, outdoor plans and utility service. The forecast team designated today and tomorrow as "First Alert" periods because conditions will affect activities, particularly along the coast.
- Expect localized coastal flooding during peak high tides; avoid low-lying coastal roads at those times.
- Secure loose outdoor items; wind gusts could cause tree limbs to fall and lead to isolated power outages.
- Allow extra time for morning commutes Sunday; heavy rain and gusty wind may reduce visibility and affect driving conditions.
- Monitor updates from local emergency management and the National Weather Service for watches or warnings.
Forecasters say the coastal storm is slow to depart, and scattered showers are likely to linger Monday before a drier, milder trend begins Tuesday into midweek. Temperatures climb into the 70s by Wednesday and Thursday, easing the immediate coastal flood threat.
Stay tuned to local media and official channels for any active alerts or changes to the forecast; tides and exact wind impacts can shift with small changes in the storm track.
