What Happened
Streets flooded across Long Island on Saturday afternoon, July 18, 2026, after hours of sustained heavy rain inundated roadways throughout the region. According to News 12 Long Island, the flooding was widespread, affecting communities across the island and prompting News 12 to send reporter Jenna Rae Gaertner into the field to assess conditions firsthand.
Gaertner was specifically dispatched to Port Jefferson, where she checked road conditions amid the flooding. Her report, filed and updated at 10:10 PM on Saturday evening, documented the scale of the flooding that had developed over the course of the afternoon and into the night. The 1 minute and 24 second video report captured conditions in the area as part of News 12’s live coverage of the storm’s impact.
Per News 12 Long Island, streets were flooded “all across Long Island” following the hours of rainfall that struck the island on Saturday. The scope of the flooding was broad enough that local leaders also weighed in — a separate News 12 segment of 3 minutes and 40 seconds featured local leaders commenting on the stormy weather conditions across Long Island.
The Saturday storm was not an isolated weather event in the region. In the days following the flooding, News 12 meteorologists were already forecasting a risk of strong storms and heavy rain Tuesday into Wednesday, following what was expected to be a sunny and warm Monday on Long Island — raising concerns among residents about additional flooding potential in the near term.
Location & Road Context
Port Jefferson, located on the North Shore of Suffolk County, is particularly vulnerable to flooding during heavy rain events due to its waterfront geography and the terrain of its surrounding streets. The Port Jefferson area sits along Long Island Sound and includes a network of local roads that can become rapidly overwhelmed during sustained rainfall.
The broader flooding event stretched well beyond Port Jefferson, with roads across Long Island affected. Drivers were urged to use extreme caution on flooded roadways throughout the region, as even shallow standing water can pose serious hazards to vehicles and motorists.

Broader Impact
The Saturday flooding came amid a stretch of active weather on Long Island, and with forecasters already signaling a renewed threat of strong storms and heavy rain by Tuesday into Wednesday, according to News 12 Long Island, the region faced the prospect of additional street flooding before conditions could fully stabilize — a reminder that repeated rainfall events can worsen drainage problems on Long Island roads that were not fully cleared from the previous storm.
