Tropical Storm Arthur, the first named storm of the 2020 Atlantic hurricane season, was named Saturday night, but is struggling with marginal sea surface temperatures and dry air.

As of 11:00 p.m. EDT Sunday, Tropical Storm Arthur was centered near 32.4°N 76.9°W, and was moving north-northeastward at about 10 mph. Maximum sustained winds were 40 knots (45 mph), with an estimated minimum pressure of 1003 mb. The center of Arthur was approximately 210 miles south-southwest of Hatteras, North Carolina. Arthur’s satellite appearance has degraded significantly on Sunday due to marginal sea surface temperatures and dry air. However, Arthur still has a narrow window to strengthen for the next 24 hours or so as it passes near the North Carolina Outer Banks. Unlike its 2014 incarnation, the latest model guidance suggests it is unlikely that Arthur’s center will make landfall in North Carolina. However, a tropical storm warning remains in effect from Surf City to Duck, NC, as well as the Albemarle and Pamlico sounds. Arthur should lose tropical characteristics on Tuesday as it turns eastward, and eventually southeastward.
