The northeastern United States faced a Saturday collision of dual weather hazards: lingering wildfire smoke from Canada finally clearing, only to be replaced by dangerous thunderstorms that have already triggered flash flood warnings across New York and New Jersey.
After a brief reprieve on Friday, smoke from Canadian wildfires returned to New York City and surrounding areas Saturday morning, degrading air quality back to unhealthy levels. The same atmospheric shifts expected to push the smoke eastward are fueling the development of powerful storm systems moving through the region.
The first round of severe weather hit northern New Jersey and New York City on Saturday, prompting the National Weather Service to issue a flash flood warning lasting through 2 p.m. Rain fell at torrential rates, with some locations measuring more than 2.5 inches in a short period. Dramatic videos from urban areas showed water streaming into Penn Station and other infrastructure vulnerable to street flooding.
Jamaica, Crown Heights, Forest Hills, Ozone Park, Brooklyn Heights, Park Slope, Woodside, and Greenpoint were among the neighborhoods dealing with either ongoing or expected flooding. The weather service elevated the tri-state area to a level 3 risk out of 5, a designation suggesting numerous severe storms rather than the typical scattered activity.
Forecasters warned that additional storm waves expected through the day could produce torrential rainfall capable of triggering flash flooding, damaging wind gusts, isolated tornadoes, and hail before conditions ease.
Meanwhile, Texas continued contending with the fallout from days of relentless rainfall that left at least two people dead and hundreds requiring rescue. Major rivers across the state were forecast to crest through the weekend, creating a secondary flooding threat even as the heavy rain ended across Hill Country.
The Devils River in southwest Texas was expected to reach major flood stage Saturday morning, potentially climbing to 22 feet when its designated flood stage is just 5 feet. The Rio Grande was forecast to peak at 21 feet by Sunday morning, with minor flooding in the Laredo area beginning at 8 feet.
Some areas of Texas received more than 2 feet of rainfall over the course of a week. Near Ozona, roughly 200 miles west of San Antonio, floodwaters overtopped Interstate 10. First responders rescued more than 50 people by boat from flooded apartment complexes, and an RV park was consumed by rising water. In Uvalde County, part of a bridge spanning the Nueces River collapsed after the region received months' worth of rain in just days.
In Cincinnati, residents of the Hyde Park neighborhood reported that heavy rain escalated into a dangerous flooding situation in as little as 20 to 30 minutes. Across multiple states, cleanup efforts continued as communities surveyed infrastructure damage left by the historic flooding event.
Author James Rodriguez: "The back-to-back weather crises hitting two entirely different regions highlight how quickly atmospheric patterns can flip from one hazard to another, leaving emergency responders stretched thin."
