ALT Sofar Ocean weather dashboard showing 0900 UTC location of Erin, and Spotter buoys (yellow hexagons) in the region. Time series of measured wave heights at bottom shows peak seas of 13.8 m occurring last night at 0416 UTC, with dominant swell from the south at 13-17 seconds.

ALT GOES-16 IR image from 1800 UTC showing location of 994 mb low pressure center across the W Atlantic and cold front extending SW and into northern Cuba. Yellow contour identifies area of seas 12 ft and greater, with wave height observations in yellow numerals.

ALT Color image of GFS wave height forecast valid 1800 UTC, with wave height contours of GFS and ECMWF wave models overlaid in fine lines, with red lines indicating 12 ft. Thick yellow contour identifies area of seas 12 ft and greater, with wave height observations in yellow numerals (feet), with estimated maximum seas of 21 ft. Green goalpost symbol shows location of Saildrone 1041 at 17Z measuring seas of 4.2 meters.

ALT Same contour for 12 ft seas and wave observations as previous images, overlaid on 1400-1500 UTC ASCAT scatterometer wind data. Red colored flags indicate wind speeds of 30-33 kt and dark blue flags indicate 34-38 kt. Bermuda is located just NW of the low center.
