A strong surface high pressure across the western Atlantic ocean resulted in windy conditions across the local area.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS SJU wrote it up.

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS San Juan, PR wrote its last area forecast discussion before the first event at Apr 19, 3:25 PM AST, 5 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 325 PM AST Fri Apr 19 2019 .SYNOPSIS...An upper level omega blocking pattern continues over the western Atlantic with a large amplitude upper level trough/low over the central Atlantic, another upper level trough/low across the eastern third of U.S. and an upper ridge of high pressure sandwiched in between them. This upper level ridge is expected to continue to build across the central and eastern Caribbean. At the surface...a frontal boundary extending from the closed low over the central Atlantic southwestward to north of the islands will slowly drift southward and may have an impact on the local weather conditions by the start of next week. && .SHORT TERM...Tonight through Sunday Night...Upper ridge mentioned before, and associated strong mid/upper level subsidence will tend to limit shower activity across the local area. Still, local effects, combined with any available moisture, will definitely play a role in the resultant weather conditions. Therefore, isolated to widely scattered nighttime and early morning showers could still be possible over the USVI and eastern PR during this period. Scattered afternoon showers could also occur over the west-central portions and west coast of the big island of Puerto Rico. The upper low over the central Atlantic, and associated frontal boundary, will continue to drift southward through this period. Strong wind flow associated with a surface high pressure ridge north of the front will help advect patches of moisture over the local area. This, coupled with enhanced low level convergence, could result in an increased in the shower activity over the USVI and eastern PR especially Saturday through Sunday Night. .LONG TERM...Sunday through Friday...Models still indicate that the low and associated frontal boundary north of the area will continue to move south with the front moving across the local islands as a "backdoor front" i.e. from the northeast Monday and Monday night. Decided to keep scattered to numerous showers...especially over the eastern half of the forecast area (eastern PR/USVI) to account for this. Too early to have a clear idea as to the amount of precip we could expect with this system, but uncertainty should diminish as the time progresses. Models also now show that there will be a frontal passage with the boundary moving to our south before dissipating Monday night. By Tuesday...the low begins to lift northward away from the northeast Caribbean. A return to a mostly easterly flow is expected which will continue to advect small patches of low level moisture from time to time. && .AVIATION...VFR conditions will prevailed across the local flying area through the fcst prd. SHRA development are expected in the vicinity of Mayaguez between 19/18z-23z, possibly affecting TJMZ/TJBQ. Brief passing SHRA cannot be ruled out across E-PR/USVI and Leeward Islands terminals at times. Winds will be from the E at 15 to 20 knots with higher gusts and sea breeze variations dropping at 10 knots or less aft 19/23z. && .MARINE...A tight pressure gradient will continue across the northeast Caribbean at least through Sunday. This will keep marine conditions on the rough side with seas up to 6 feet and winds in the 15 to 20 knots range. Although there is no a small craft advisory in effect at this time...small craft operators are advised to exercise caution while navigating over the coastal waters. The risk of rip currents remains up to moderate for many beaches in PR and USVI. Nevertheless, even if the risk is low...beachgoers are also urged to exercise caution when entering the water as rip currents could develop unexpectedly. && .PRELIMINARY POINT TEMPS/POPS... SJU 75 87 75 85 / 20 30 40 40 STT 75 87 75 86 / 20 30 40 30 && .SJU WATCHES/WARNINGS/ADVISORIES... PR...None. VI...None. AM...None. && SHORT TERM...RGH LONG TERM....RGH
