Post Date:06/07/2023 11:05 AM

3:35pm Update - The EPA provides information and suggestions on keeping you and your family safe during times of wildfire smoke exposure:

Wildfires and Indoor Air Quality 

-----------------------------------------------------------------------

The CT Department of Emergency Services and Public Protection, Division of Emergency Management and Homeland Security (DEMHS) is tracking an area of very dense smoke expected to move into Connecticut this afternoon and continue into Thursday morning.

As of 10:15am, smoke from Canadian wildfires continues to be present here in Connecticut. Air quality conditions are currently deemed “unhealthy” with AQI values of 150 170PM 2.5

DEMHS are monitoring an area of very dense smoke positioned throughout Upstate New York and northern Pennsylvania. This area of dense smoke is modeled to move into Connecticut over the next few hours with higher smoke density expected than what was observed yesterday.

AQI values will likely stay between 150 200PM 2.5, however within the highest concentrations of smoke the AQI level could possibly increase to “very unhealthy” with is an AQI value over 200PM 2.5.

The Connecticut Department of Energy and Environmental Protection (DEEP) has issued an Air Quality Action Day for fine particulates through midnight tonight. An Air Quality Action Day means that fine particulate concentrations within the region may approach or exceed unhealthy standards.

The highest concentrations of smoke are expected to stay in Connecticut through the evening and into the early morning hours of Thursday. Lower concentrations of smoke will linger through much of Thursday. DESPP / DEMHS will continue to monitor conditions and provide any updates as warranted.

Stamford Purple Air monitors which measure air quality and the EPA fire and smoke map show fine particulate matter is high indicating unhealthy levels. When particulate matter levels are elevated, people should refrain from strenuous outdoor activity, especially sensitive populations such as children, older adults and persons with respiratory problems.
