Hudson Valley weather: Warm, sunny and hazy Aug. 4 in Westchester, Rockland, Putnam
The Lower Hudson Valley can expect some warm and sunny weather for the first full week of August, but residents will want to be ready for air quality issues due to Canadian wildfires.
The National Weather Service issued an air quality alert for Westchester, Rockland and Putnam counties Monday, Aug. 4, valid until midnight Aug. 5, thanks to raging wildfires up north in Canada.
Lower Hudson Valley air quality alert Monday, Aug. 4
NYSDEC said ground level ozone and particulate matter in the air due to wildfires in Ontario could exceed safe air quality index levels over 100.
As of 9:45 a.m., measured the Lower Hudson Valley's Air Quality Index as "Moderate," with an AQI score of 74, an Ozone level of 14 and a particulate matter level of 101.
NYSDEC says the risk for individuals who may be prone to respiratory illness was expected to increase as the day continues, and temperatures rise.
At-risk populations for poor air quality include "the very young, and those with preexisting respiratory problems such as asthma or heart disease," said NWS in the alert.
NYSDEC said those at risk should stay inside and limit physical activity.
Sunny skies and warm temperatures to kick off August
Despite air quality issues, Monday is presenting itself to be a beautiful day. There will be some widespread haze due to the smoke from the Canadian wildfires, but skies will be sunny with high temperatures near 89 degrees.
Overnight, the haze is expected to stick around with partly cloudy skies and lows near 66 degrees.
Tuesday and Wednesday should look similar to Monday. Tuesday should bring mostly sunny skies with high temps near 88 in the day and lows near 66 overnight.
Wednesday should also be sunny, with a bit more clouds in the sky and lower temperatures compared to the beginning of the week, near 84 degrees. Overnight will be mostly cloudy again with temperatures at a steady 66 degrees.
