Arthur formed as a tropical wave off the coast of Africa on 18 July 1990. A maximum flight level wind speed of 47 mph just northeast of the center at an altitude of 1500 foot and a maximum surface wind of 46 mph was estimated, along with 1005 mb surface pressure. This data in combination with satellite intensity estimated were the bases for upgrading the depression to Tropical Storm Arthur. Arthur, which was the second tropical storm of the 1990 Atlantic hurricane season on the 25th July 1990, hit both the island of Tobago and Grenada.
