Although relatively tranquil seas were observed across the local waters on May 27th, the sea breeze along the north-central coastal areas of Puerto Rico promoted a moderate risk of rip currents.
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 May 27, 5:27 PM AST, 43 minutes earlier.
Area Forecast Discussion National Weather Service San Juan PR 527 PM AST Sat May 27 2023 .SYNOPSIS...A plume of moisture will continue to move across the region tonight and into tomorrow promoting above normal precipitable water (PWAT) values up to around 2.2 inches. Showers and possibly isolated thunderstorms will move from the Anegada Passage into other local waters and windward sectors from tonight and another active afternoon is expected tomorrow. A limited to possibly elevated risk of excessive heat is expected for the next several days, mainly for the lower elevations across northern and western Puerto Rico. && .SHORT TERM...Tonight through Monday... Satellite derived precipitable water (PWAT) values currently show normal values around 1.8 inches across the region, with a plume of moisture filtering into the area from the east with above normal values currently as high as 2.1 inches. This plume will continue to move across the region promoting moist weather under east to southeast winds, although becoming more easterly tonight and tomorrow. It will also will reach PWAT values up to around 2.2 inches, above normal values for this time of the year. Shower activity will reach sectors of the eastern region this evening and tomorrow morning as the moist plume closes in. This afternoon's activity, currently over the western half of Puerto Rico, should continue to gradually dissipate this evening. Ridging remains aloft, somewhat limiting convective development. However, as we enter the afternoon hours tomorrow, available moisture from the plume, diurnal heating and local effects will still promote convective activity with up to heavy rain and isolated thunderstorms along the interior and over western Puerto Rico. Streamers from the local islands and from El Yunque are also possible and could affect the eastern region including the metro area during the afternoon. This could result in ponding of water on roadways and poorly drained areas. Current model guidance indicates somewhat drier conditions late tomorrow and on Monday, Memorial Day. However, local and diurnal effects will once again promote convective activity mainly focused over west-northwest Puerto Rico. A limited to possibly elevated risk of excessive heat is expected for the next several days with heat indices possibly reaching above 108 degrees, mainly for the lower elevations across northern and western Puerto Rico. .LONG TERM...Tuesday through Saturday... ./FROM PREV DISCUSSION...Issued at 348 AM AST Sat May 27 2023/. A weak mid-to upper-level ridge pattern is expected to prevail over the islands through the long term period. This will keep the 500 mb temperature relatively warm, around minus 5 degrees Celsius and promote drier air aloft, limiting the vertical development of showers. However, isolated thunderstorms are expected to develop each afternoon over portions of western PR due to the combination of the available low level moisture, daytime heating, and the sea breeze convergence. Heat indices should increase between 108-111 degrees Fahrenheit, triggering Heat Advisory criteria once again across portions of the lower elevations of northern and western PR, as winds acquire a southeasterly wind component from Tuesday onwards. In terms of moisture content, PWAT values are expected to remain between 1.50-1.75 inches through at least Thursday, increasing near 2.00 inches from Friday into the weekend. Therefore, seasonal weather conditions should prevail across the islands in general, with passing showers moving across windward areas during the night and early morning hours, followed by diurnally induced afternoon showers with isolated thunderstorms over western PR each day, and increasing in coverage late in the forecast cycle. && .AVIATION...SHRA/sct TSRA to cont thru 28/00Z and then dissipate ovr land. A plume of moisture will increase activity ovr ern PR and the USVI. Expect sct SHRA and isold TSRA thru 28/10Z ovr ern PR and thru 28/18Z arnd the USVI. Mtn obscurations and MVFR/IFR conds in SHRA. Low level winds SE 10-15 kt with sea breezes bcmg by 28/01Z land breezes less than 6 kt. SHRA/TSRA will return aft 28/17Z to wrn and interior PR. Max winds W-NW 45-55 kts btwn FL380-450. && .MARINE...Seas up to 5 feet or less are expected for the offshore Atlantic waters and Anegada Passage tonight, seas 4 feet or less elsewhere. Light to moderate southeast winds are expected tonight, becoming more easterly by tomorrow, Sunday, and through early next week. Relatively tranquil seas are expected to persist during the next several days. However, tonight into tomorrow, showers with isolated thunderstorms are expected from the Anegada Passage into the local waters, resulting in locally higher seas and winds. There is a moderate risk of rip currents for the beaches of northern Puerto Rico, as well as for some beaches of St. Croix and Culebra. && .SJU WATCHES/WARNINGS/ADVISORIES... PR...None. VI...None.
