Friday, May 17, 2024 DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY THROUGH 1000Z May 18, 2024 SMOKE: Canada/North Central and Northeastern United States/Greenland/Atlantic Ocean... Numerous large wildfires located throughout portions of Canada from the southern regions of the Northwest Territories and northeast British Columbia to the central regions of Alberta, Saskatchewan and Manitoba continued to burn despite being concealed by persistent cloud cover throughout the day. Due to the large amount of ongoing wildfires and recently developed ones throughout these areas, a large mass of smoke ranging from light to thick density covered a majority Canada, extending from the western part of the Northwest Territories into central Nunavut where it continued southeastward into Manitoba. The thickest density smoke continues to be seen surrounding the larger fires located in the northeast corner of British Columbia, north-central Alberta, eastern Alberta, east-central Saskatchewan and west-central Manitoba. Areas of moderate smoke were also seen covering portions of north-central Canada, north-central U.S. and areas northeast of Quebec, extending into southern Greenland. A large amount of cloud cover throughout these regions did not allow for further smoke analysis this evening. United States Pacific Northwest... Fire activity was observed throughout the US Pacific Northwest. Several light to density smoke plumes were seen in southern Oregon and one moderate density plume was also seen in the northeastern corner of California. AEROSOL/SMOKE: Central-Southern Mexico/Gulf of Mexico/Central America/Yucatan Peninsula/Florida/Atlantic Ocean/Cuba/Jamaica/Pacific Ocean... A large area of predominantly light to moderate density smoke attributed to widespread seasonal fire activity throughout central-southern Mexico, the Yucatan Peninsula and Central America was observed today from the Gulf of Mexico, northeast through Florida and extending east into the northern Atlantic Ocean. The large area of aerosol/smoke continued expanding south through central-southern Mexico, Central America and into the Pacific Ocean off the southwest coastline of Mexico. Areas of higher density smoke and aerosols were observed over northern Central America, the Yucatan Peninsula and the Gulf of Mexico. Aerosols from a composite of volcanic emissions and industrial sources in Mexico, and gas flaring activity in the Bay of Campeche contributed to the expansive area of aerosol/smoke observed throughout these regions today. Willkens 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
