Dirty rain to dump toxin-riddled water on NYC but theres an upside: experts

Toxin-riddled “dirty rain” will pour on the Big Apple on Saturday — but at least it will be quick and flush out the unhealthy haze that wafted in from the Canadian wildfires, experts say.“There’s a lot of smoke and particulate matter in the air, so as we get rainfall, those water droplets are going to pick up some soot, some ash, and bring that to the ground,” AccuWeather’s Senior Meterologist John Feerick told The Post on Friday.“At least initially, you’re probably gonna have a little bit of dirty spots or soot on cars and stuff like that.“But it’s going to be relatively short-lived,’’ he said.“The heavy downpours that we get will just wash that away.”Feerick said the dirty rain is actually less concerning than the intensity of the summer storm initially bringing it to the area.Thunderstorms and damaging winds are forecast till Saturday night — with some gusts reaching as high as 65 mph.The rain will fall as much as 2 inches per hour.“The greater concern is going to be flooding downpours, localized flash flooding,’’ the meteorologist said.“Streets in New York — you know how they get as far as streets filling up with water pretty fast.’’The storm is set to roll through the five boroughs in the mid- to late-morning Saturday — when the air quality is expected to spike close to “very unhealthy” levels.The precipitation, having been hovering in the toxic air, will drag down the dust, soot, metals and other minuscule toxins that traveled hundreds of miles from the Canadian wildfires to the metro area.The initial rain will leave dirty remnants along the streets and cars, but the following rounds of rain will quickly wash the filth away, Feerick said.The wet, damp front will move out of the Big Apple on Saturday night, and the humidity will plummet by Sunday morning.Sunshine is also predicted for the tail end of the weekend.“It doesn’t look like we’ll have the air quality issues that we’ve had,’’ Feerick said...
