In late May, a broad area of cyclonic flow was centered over the southwestern Caribbean Sea amidst enhanced low-level moisture near the East Pacific ITCZ axis.[1][2] A surface trough steadily developed in association with this system, producing scattered convection and winds in conjunction with diffluence aloft and high surface pressure to its east.[3][4] Organization fluctuated for several days due to variable upper-level wind shear and dry air entrainment into the low-level center.[5] At the time, the broad disturbance remained nearly stationary in the central Caribbean, with strong showers and thunderstorms confined to the east over much of the Greater Antilles.[6]
Preparations
As rainfall associated with the precursor disturbance began to affect the Greater Antilles, a flash flood watch was to remain in effect for low-lying and flood-prone areas in Jamaica until June 4, 17:00 local time.[7] However, the watch was upgraded to a warning the next day as torrents continued to affect the island.[8] Authorities in Haiti issued an orange alert on June 3, warning of moderate to severe rainfall impact; transportation and flight services in the southern part of the country were suspended.[9] Meanwhile in the neighboring Dominican Republic, 21 of 31 provinces were put under bad weather alerts, ranging from very high (red) to low (green) flood risk.[10] A flood watch was also issued for the northern coast of Puerto Rico, and local marine interests were urged to secure their vessels due to rough sea conditions.[11]
