The National Weather Service in San Juan has issued a * Flash Flood Watch for Puerto Rico and the U.S. Virgin Islands including Culebra and Vieques * From Monday noon through Tuesday evening * There is a high risk for flash flooding across Puerto Rico and the U.S. Virgin Islands starting on Monday afternoon through Tuesday evening. The passage of an active tropical wave will result in periods of heavy shower and thunderstorm activity across the region. The bulk of this activity will favor the eastern half of Puerto Rico, as well as the U.S. Virgin Islands through the period. However, diurnal heating and local effects will enhance shower and thunderstorm activity across the interior and western sectors of Puerto Rico during the afternoon hours. Overall, rainfall totals are forecast to range between 2 and 4 inches with isolated amounts up to 6 inches in Puerto Rico. Rainfall totals between 1 and 2 inches with isolated higher amounts are expected across the U.S. Virgin Islands. This will cause guts and small streams to overflow their banks and some larger rivers to rise above flood stage. Some of these rises will happen very rapidly when thunderstorms dump heavy amounts in a short period of time. There is also a possibility of mudslides in steep terrain after the first 24 hours of rainfall. Moisture associated with this tropical wave will continue into Wednesday with some heavy rains indicated so the the watch will be extended if needed on Tuesday. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. && $$ ICOLON/SNELL

What forecasters said that day
The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS JSJ wrote its last area forecast discussion before this flash flood watch went out at Jul 28, 10:27 AM CDT, 4 hours 26 minutes earlier.
Area forecast discussion, Jul 28, 10:27 AM CDT, 4 hours 26 minutes before
Area Forecast Discussion National Weather Service San Juan PR 1127 AM AST Sun Jul 28 2019 .UPDATE...A few showers affected portions of eastern and northern PR in the morning hours, but have since diminished. The satellite imagery indicates some cloudiness developing across the higher elevations of the local islands and streaming to the WSW under the prevailing ENE wind flow. The latest guidance insists in shower and thunderstorm development across portions of SW-PR this afternoon, with isolated to scattered showers elsewhere. Minor changes were made to the inherited forecast to account for the increase in moisture and the increase in precip forecast by the high resolution models. The tropical wave is still expected to move in late tonight, but some rainfall bands may start moving into the local waters later this afternoon. Thunderstorms are being observed with this tropical wave and thus no changes were made to the forecast for the overnight period since it already shows a gradual progression of increased shower and thunderstorm activity. && .AVIATION...VFR conds expected across the local area through 28/17Z. VCSH expected across many of the local terminals for the rest of today and tonight, but VCTS is expected for TJMZ this afternoon. As the tropical wave moves in, VCSH/VCTS is to be expected this evening across TKPK and TNCM, then gradually approaching TIST and TISX later tonight. && .MARINE...Small craft operators are urged to exercise caution across the nearshore Caribbean waters of PR due to winds up to 20 knots. Seas will be up to 5 feet the rest of today and tonight, increasing on Monday as the tropical wave approaches. Showers and thunderstorms associated with the tropical wave will affect the local waters starting tonight. && .PREV DISCUSSION... /issued 440 AM AST Sun Jul 28 2019/ SYNOPSIS...Light passing showers early this morning should brush the northern coast of PR and the USVI. Diurnally induced afternoon convection will follow over west/southwest PR. Shower and thunderstorm activity will increase from Monday through Wednesday due to the passage of two tropical waves. Another wave is expected on Friday. Hazy skies due to Saharan dust return briefly on Thursday and once again during the weekend. SHORT TERM...Today through Tuesday... A fairly stable weather pattern is expected to prevail across the area for today as a drier than normal air mass remains in place. However, patches of low-level moisture embedded within the easterly trade wind flow will continue to move across the area from time to time through this afternoon. This will result in some passing showers across portions of northern and eastern Puerto Rico through the early morning hours, followed by the development of showers and isolated thunderstorms across western Puerto Rico during the afternoon hours as the low-level moisture combines with the strong daytime heating and sea breeze convergence. In terms of the Saharan dust concentration, the good news is that the concentration will be much lower today compared to previous days. Attention will then turn to a vigorous tropical wave, currently located over the Lesser Antilles, that will be approaching the area tonight. Moisture will increase in earnest starting this evening across the USVI and later during the overnight hours across eastern Puerto Rico. Latest model guidance indicates precipitable water values increasing to as high as 2.30 inches, which is around 2 standard deviations above normal for July. Therefore, conditions will be favorable for the development of deep and organized convection. Showers and thunderstorms are expected to increase in coverage across the USVI later this evening and across eastern Puerto Rico during the overnight hours. Then, during the day on Monday, widespread showers and thunderstorms are expected to affect the local area with activity expected to cluster across the USVI and eastern Puerto Rico during the morning hours and then extend into western Puerto Rico into the afternoon hours. The potential will exist for urban and small stream flooding as well as rapid river rises and mudslides in areas of steep terrain across areas that receive a prolonged period of heavy rainfall activity. The unsettled weather conditions will continue into Tuesday as precipitable water values continue to remain above 2.0 inches. The low-level flow will become southeasterly. Therefore, activity is expected to cluster across portions of southern and eastern Puerto Rico and the USVI during the morning hours. Then, depending on the amount of sunshine that develops, additional activity is expected across the northwest quadrant of Puerto Rico during the afternoon hours. Once again, urban and small stream flooding as well as rapid river rises and mudslides in areas of steep terrain will be a concern. Generally speaking, this tropical wave that will be affecting the area during the first part of the work week promises to bring beneficial rains to areas that have been suffering from significant drought conditions during the last several weeks to months. LONG TERM...Wednesday through Sunday... Another tropical wave streams quickly on Wednesday, the flooding threat will remain high due to saturated soils from the previous days heavy rainfall. Models indicate high precipitable water content across the USVI/Eastern sections of PR between the morning and afternoon hours. A drier air mass with Saharan dust filters after the wave passage, creating hazy skies and fair weather conditions through Thursday. However, diurnally induced afternoon showers can not be ruled out over western PR. By Friday, another tropical wave but not as vigorous as the previous waves will bring scattered showers and isolated thunderstorms across the region. Breezy conditions and another drier air mass with Saharan dust are expected to prevail during the weekend. Although moisture decreases during the weekend, the combination of the available low level moisture, daytime heating and sea breeze convergence will result in showers and possible isolated thunderstorms over the western sections of PR each afternoon. AVIATION...Mainly VFR conditions to prevail through most of the period. SHRA/TSRA expected across western PR between 28/16z and 28/22z, affecting mainly the vicinity of TJMZ. TEMPO MVFR conditions are possible. A tropical wave will bring an increase in SHRA/TSRA activity across the Leeward Island terminals after 28/21z and across the USVI terminals after 29/00z. Winds light and variable through 28/13z, increasing to 10 to 20 kts with higher gusts and sea breeze variations after 28/14z. MARINE...Seas will continue at less than 5 feet and east- northeast trades should range between 10-15 knots today. However, winds up to 20 knots are possible across the Caribbean coastal waters of PR and small crafts should exercise caution across these waters. Squally weather is expected from Monday through Wednesday due to the passage of two tropical waves.

...Active thunderstorms still have potential to generate
landspouts...
At 206 PM AST, thunderstorms stretched from Cabo Rojo to Penuelas
and southern Adjuntas. The thunderstorms were drifting slowly west
southwest.
The strongest area was over Punta Guanaquilla. One funnel has been
reported to the National Weather Service although it had not yet
touched the ground.
Conditions in the atmosphere are such that weak, brief funnels may
form this afternoon. They usually develop beneath showers or weak
thunderstorms when the air aloft is especially cold or the surface
is especially warm.
These funnels are usually harmless, but on rare occasions can briefly
touch down and cause wind gusts over 50 mph. If a funnel approaches
your location, move indoors.
Please contact the National Weather Service if you see a funnel.
