Later in the day, a portion of the tropical cyclone’s low-level circulation became partially exposed, due to northwesterly wind shear across that region.<\/p>\n GOES-16 Infrared Window (11.2 \u00b5m<\/strong><\/a>) images (below)<\/strong><\/em> include contours of deep-layer wind shear<\/strong><\/a> valid at 2200 UTC from the CIMSS Tropical Cyclones<\/strong><\/a> site — which displayed the shear that was affecting Karl and helping to partially expose its low-level circulation.<\/p>\n<\/a><\/a>
