DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY
THROUGH 1600Z July 3, 2022
SMOKE: Alaska/Arctic Ocean/Western & Central Canada/Central & Eastern CONUS/Maritime Canada/Atlantic Ocean… Ongoing widespread wildfire activity in Central Alaska and northwestern Canada is responsible for an expansive area of varying density smoke that extends from central Alaska northwest and north out across the Arctic Ocean and then back south into the Yukon and Northwest Territory. From here, the smoke is moving westward back across the Northwest Territory and Yukon until it is either picked up by flow main flow dragging the majority of smoke east-southeast or moves southwest into British Columbia, from where the smoke is making it into the Gulf of Alaska before entering the Pacific Northwest. Following the main stream east-southeast, the smoke then crosses into the southern Prairie Provinces, northern Plains, and Great Lakes. The smoke then rounds the base of a trough over Quebec and moves east-northeast between the St. Lawrence River and the Mid-Atlantic, including New England and the Maritime Provinces. The smoke extends as far east out into the Atlantic as southern Greenland. The exact eastward extent is uncertain due to extensive cloud cover over much of the North Atlantic. Northern Mexico/Southern & Central Plains… Remnant thin to moderate smoke, likely with contributions from seasonal fire activity in Mexico and possibly Alaska (described above),was analyzed covering an area from northern Chihuahua and northern Coahuila northeast across Texas and Oklahoma and into Missouri and southern Indiana. It is possible this area of smoke could be merging with the larger area of smoke described above taking the upper jet crossing the Ohio River Valley and merging over the Mid-Atlantic. DUST: Tropical Atlantic/Caribbean Sea/Central America... An area of Saharan Dust was seen blanketing much of the North Atlantic Ocean this morning from the Canary Islands to south of Bermuda, with the dust covering nearly all of the Caribbean Sea as well. The layer likely extends into Central America as well. Hosley THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS OF SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE, TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE: JPEG map: https://www.ospo.noaa.gov/data/land/fire/currenthms.jpg Smoke data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Smoke_Polygons Fire data: https://satepsanone.nesdis.noaa.gov/pub/FIRE/web/HMS/Fire_Points ANY QUESTIONS OR COMMENTS REGARDING THIS PRODUCT SHOULD BE SENT TO: SSDFireTeam@noaa.gov
