were issued by the National Weather Service office in San Juan, Puerto Rico. On April 19, another tropical depression formed over the southwestward Caribbean. The depression moved northeastward through the following day, before doubling-back to the southwest and dissipating by April 21. Another previously unnumbered tropical depression formed over the Bay of Campeche on June 17. It made landfall in Mexico south of Tampico before dissipating about two days later. A fourth unnumbered tropical depression developed near Andros on July 2. It made landfall in southeast Florida and later in South Carolina before dissipating on July 4. The depression dropped up of rainfall in Broward County, Florida, causing localized flooding. A waterspout-turned-tornado at Port Everglades overturned a shed and downed some power lines. Heavy precipitation also fell in South Carolina, especially in Clarendon and Sumter counties, inundating crops and flooding some cars, homes, a school, and stores in the Mayesville area. Storm names The following list of names was used for named storms that formed in the North Atlantic in 1981. It was the first use for all of these names since the post-1978 naming change, except for Arlene, Cindy, and Irene, which had been previously used in 1959, 1963, 1967, and 1971. There were no names retired this year; thus, the same list was used again in the 1987 season. Season effects This is a table of the storms in 1981 and their landfall(s), if any. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but are still storm-related. Damage and deaths include totals while the storm was extratropical or a wave or low. |- | Unnumbered || || bgcolor=#| || Unknown || Unknown || || || || |- | Unnumbered || || bgcolor=#| || Unknown || Unknown || || || || |- | Arlene || || bgcolor=#| || || || Cuba, Bahamas || Minimal || || |- | Two || || bgcolor=#| || || || Southern United States (Texas), Midwestern United States, Maryland || $4 million || 3 || |- | Unnumbered || || bgcolor=#| || || Unknown || || || || |- | Bret || || bgcolor=#|Tropical storm || || || Old South (Virginia), Kentucky, Maryland, Pennsylvania, Midwestern United States || Minimal || 1 || |- | Unnumbered || || bgcolor=#| || || Unknown || || || || |- | Four || || bgcolor=#| || || || Mexico,
