What happened
The episode as NWS SJU wrote it up.

During the late afternoon through early evening hours, the shower activity then became focused across the municipalities of North Central PR.

Area forecast discussion, Feb 4, 2:00 PM AST, 4 hours before
Area Forecast Discussion National Weather Service San Juan PR 200 PM AST Sat Feb 4 2017 .SYNOPSIS... The proximity of the subtropical jet will induce upper level perturbations across the region through early next week. At the surface, surges of moisture will move across the region at times. These surges will interact with the upper level disturbance to produce periods of clouds and shower each day across the islands. A ridge pattern is expected to return around the upcoming mid week. && .DISCUSSION... A surge of moisture with clouds and showers is moving across the region. This moisture will produce showers in the form of streamers downwind from the islands of the U.S. Virgin Islands and across Eastern Puerto Rico during the next few hours. In addition, the available moisture will interact with the local topography, diurnal effect and sea breeze convergence to produce scattered to numerous showers over the West and Interior PR. Urban flooding is possible in isolated spots of Northwestern PR and the San Juan Metro Area later today. Trade winds will continue to enhance moisture advection across the eastern Caribbean. A ridge pattern will build across the forecast area by the upcoming mid week. && .AVIATION... VFR conds will prevail across the flying area thru the forecast period. Brief MVFR cigs possible near TJMZ and TJBQ between 04/18-21Z with the afternoon SHRA. East winds at 10-20 kts will continue below FL050. && .MARINE... Mariners can expect winds of 10-15 kts and seas of 3-5 feet in the nearshore waters and 4-6 feet in the offshore waters. Therefore...small craft operators should exercise caution across the offshore waters. Winds and seas are expected to increase around 15-20 kt and 7 foot by early next week. && .PRELIMINARY POINT TEMPS/POPS...

- Flood
- Flooding that develops more slowly than a flash flood: rivers leaving their banks, or water standing over land for an extended time.
- Flash Flood
- Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
After NWS Directive 10-1605, the rules offices file Storm Data by.
