WSWhat forecasters said that day
The local office's own words before this flash flood warning 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 warning went out at Jul 2, 4:33 AM CDT, 5 hours 51 minutes earlier.
Area forecast discussion, Jul 2, 4:33 AM CDT, 5 hours 51 minutes before
Area Forecast Discussion
National Weather Service San Juan PR
533 AM AST Sat Jul 2 2022
.SYNOPSIS...The passage of a strong tropical wave will lead to
increased wind speeds and widespread shower and thunderstorm
activity today into Sunday. This scenario will increase the
potential for urban and small stream to localized flash flooding
and mudslides. In addition, moderate to locally strong winds will
maintain choppy to hazardous marine and surf zone conditions. As a
result, Small Craft Advisories and High Risk of Rip Currents
remain in place for most local waters and beaches, respectively.
Weather and marine conditions will gradually improve by early next
week.
&&
.SHORT TERM...Today through Monday...
The best convection of a tropical wave approaching the area is about
290 miles southeast of San Juan. The wave is expected to pass
through the U.S. Virgin Islands today and Puerto Rico overnight. The
forecast for this wave has changed very little in the past 24 hours.
The 850 mb winds forecast both before and after the wave reach 30-35
knots over Puerto Rico and the USVI. Precipitable water values are
expected to peak twice, once at 6 AM Sunday and again just after 6
PM AST at 2.3 inches. There will be a rapid ramp-up on Saturday to
these maximum values, however during the day today. This will
provide more than adequate moisture for heavy rains. Although not
very unstable, 500 mb temperatures are expected to be around minus 7
degrees today, dropping to minus 6 on Sunday. Moisture and showers
will move into the area from the southeast, and are already
affecting Saint Croix. Only scattered showers in southeast and
eastern Puerto Rico are expected before dawn, but showers should
spread rapidly across the area during the morning. Currently rain
amounts for the next 48 hours should range from 1 to 4 inches--
lowest northwest and highest southeast. This will likely provoke
urban and small stream flooding with rapid river rises later in the
day and overnight. As flow turns southeasterly after the passage of
the wave, good moisture will continue to stream across the area
tonight and into Sunday with the threat of minor flooding
continuing, but low-level moisture drops off quickly by Sunday
morning. Heavy showers will likely form during the day Sunday, but
will move quickly. More typical summer weather conditions will
return in a breezy scenario Monday.
The upper level low in the long wave trough is quickly lifting
northeast of the British Virgin Islands but is also dissipating.
Some troughiness will remain across eastern Cuba and Hispaniola as
the main trough feels the presence of the cut-off low south of
Florida and Cuba. This will produce a slightly more favorable
environment for enhanced shower and thunderstorm activity today and
Sunday, though its effects are waning. High pressure will move in
over the Antilles on Monday as the atmosphere begins to dry.
.LONG TERM...Tuesday through Saturday...
At the surface, a strong high pressure across the north Atlantic
will induce a generally east to southeast wind flow of around
10-20 mph and locally higher through the cycle. Variations in the
general wind flow will result from a weak tropical wave crossing
the northeastern Caribbean by Wednesday. Lingering moisture from a
departing strong tropical wave will maintain above-normal moisture
levels of 2.0 inches or above through Tuesday night. After that, a
patchy weather scenario and somewhat drying trend will follow,
promoting a more stable weather pattern. Even considering a slight
increase in tropical moisture with the passage of a weak tropical
wave, the moisture content will remain at normal seasonal levels,
ranging between 1.4 and 1.9 inches.
Despite variations in surface winds and moisture content, a set of
mid-to-upper level lows streaming across the northeastern
Caribbean will maintain a weak trade wind cap and somewhat
favorable conditions for deep convective development through most
of the cycle. Aided by local and diurnal effects, this scenario
will enhance afternoon showers and isolated thunderstorm
development mainly across the interior to western sections of
Puerto Rico, even during the driest periods expected on Wednesday
and Thursday. Streamer-like showers could also affect portions of
eastern Puerto Rico and the San Juan metropolitan area each
afternoon. Although limited, overnight and early morning trade
wind showers will offer the chance for measurable rainfall amounts
across the U.S. Virgin Islands and eastern Puerto Rico. Saharan
Dust concentration will maintain hazy conditions, with the
