The episode as NWS SJU wrote it up.
Troughs at different levels of the atmosphere helped thunderstorms develop during the afternoon over the interior and northwest sections of Puerto Rico, and between eastern PR and the U.S. Virgin Islands. Rainfall amounts were generally between 2 and 3 inches with the heaviest showers. Flooding was reported over the eastern interior.

NWS San Juan, PR wrote its last area forecast discussion before the first event at Jun 5, 4:27 PM AST, 1 hour 48 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 427 PM AST Wed Jun 5 2024 .SYNOPSIS... Troughiness at different levels across the northeastern Caribbean will continue to enhance shower and thunderstorms development across the regional waters and portions of the islands through early Thursday. A Saharan Air Layer will bring drier air and Saharan dust across the local area from tomorrow onwards. Hazy conditions are expected mainly on Thursday and Friday. Hot temperatures are expected through the weekend. && .SHORT TERM...Today through Friday... Thunderstorms developed this afternoon over the interior and northwest sections of Puerto Rico, and between eastern PR and the U.S. Virgin Islands. Rainfall amounts were generally between 2 and 3 inches with the heaviest showers. High temperatures were between 88 and 94 degrees across the lower elevations of the islands with heat indices ranging between 108-116 degrees before the onset of afternoon convection. Winds were from the southeast at 10 to 15 mph with gusts between 22-24 mph across coastal areas. A mid-to upper-level trough pattern to our north/northwest will continue to aid in the development of showers and thunderstorms across the local area through at least early Thursday. At lower- levels, a moist southerly wind flow prevails and showers could still move at times over land areas through Thursday morning. Although a drier air mass with Saharan dust is expected to gradually filter from the east on Thursday, afternoon convection is expected to develop once again across portions of the interior and the northwest quadrant of Puerto Rico. Hazy skies are also expected in general across the local area through Friday, with the peak of the event on Thursday. Having said that, a gradual decrease in shower activity is expected between late Thursday and Friday. The available low-level moisture content and the southeasterly winds will promote hot conditions across the islands during the next several days, particularly across St. Croix and most coastal municipalities of western and northern Puerto Rico. .LONG TERM...Saturday through Wednesday.../From Prev Forecast The latest model guidance continues to suggest a dryer and more stable weather pattern across Puerto Rico and the U.S. Virgin Islands as a deeply layered ridge prevails just east of the Leeward Islands through the weekend. The NASA Dust Aerosol Optical Thickness model indicates the presence of Saharan Dust particles over the area. Currently, the concentrations do not surpass 0.20. Therefore, it is not considered as a slight to moderate dust event, and we did not add it to our forecast grids. Nevertheless, people will experience hazy skies, and sensible people with respiratory illnesses could still be affected. The latest Precipitable Water (PW) models suggest values decreasing to normal, even below normal climatological levels for this time of the year. Most recent guidance also shows dry air at the mid-levels of the atmosphere and the 500 mb temperatures around -5 degrees Celsius, meaning that if any rainfall activity does develop, it will not grow much vertically. Therefore, we do not anticipate unstable conditions through the weekend. However, we cannot rule out the typical afternoon convection across the islands. By Tuesday into midweek, we foresee a slight increase in moisture as the Saharan Dust moves out of the area and patches of moisture associated with another tropical wave reach the island. Overall, during the long term, we forecast mostly stable weather conditions across the islands, with southeasterly to east- southeasterly winds. With this weather pattern, we anticipate warm temperatures, and we cannot rule out the possibility that heat products like advisories and warnings will be issued along the lower elevations and urban areas. We encourage citizens and visitors/tourists to stay updated with our latest weather forecasts. && .AVIATION...
