Flash flood warnings have struck the north-eastern US as severe thunderstorms follow smoky skies from Canadian wildfires, bringing dangerous weather to the region. Saturday is delivering a double dose of hazardous conditions, with torrential rain and unhealthy air quality impacting millions. Residents should prepare for ongoing threats as storms sweep through.
Wildfire Smoke from Canada Returns to Northeast
After a brief break on Friday, wildfire smoke from Canada moved back into New York City and surrounding communities on Saturday. Air quality levels have returned to unhealthy ranges, prompting health advisories. The smoke is expected to gradually improve as shifting winds push it away, but these same winds are fueling a new threat.
Severe Thunderstorms Trigger Flash Flood Warnings
The first wave of powerful storms moved through northern New Jersey and New York City, prompting a flash flood warning through 2pm. Videos shared on social media showed water pouring into parts of the city’s vulnerable infrastructure, including Penn Station. By the afternoon, more than 2.5 inches (6 cm) of rain had fallen in some locations, with flooding underway or expected in affected areas.
Neighborhoods including Jamaica, Crown Heights, Forest Hills, Ozone Park, Brooklyn Heights, Park Slope, Woodside, and Greenpoint were among those impacted. Forecasters warn the storms could produce torrential rainfall capable of causing flash flooding, damaging wind gusts, and even isolated tornadoes. Hail is also possible.
| Weather Threat | Impact Level | Affected Areas |
|---|---|---|
| Flash Flooding | High | New York City, New Jersey |
| Wildfire Smoke | Unhealthy | NYC, surrounding communities |
| Severe Thunderstorms | Level 3 (out of 5) | Tri-state area |
Key Takeaways for Residents

Texas Continues to Battle Historic Rainfall
Meanwhile, Texas continues to battle the aftermath of days of destructive storms and historic rainfall.
