The episode as NWS SJU wrote it up.
Tropical Storm Earl moved north of Puerto Rico early in the month. Although the storm never made landfall, it was responsible for shifting the local wind flow from the south. The islands were under this moist flow for around a week. Adding local effects to the mix, active afternoons were observed, with strong showers and thunderstorms. Several flood and mudslide reports were received.

Area Forecast Discussion
National Weather Service San Juan PR
1109 AM AST Sun Sep 4 2022
.UPDATE...
The core of Tropical Storm Earl is now located just outside of
the northeast corner of the forecast region, about 75 to 100 miles
northeast of the Virgin Islands. The track remains mostly the
same with this system exiting our domain by late tonight, then
moving north into the Atlantic where it's impacts will decrease
significantly. Two main convective bands stretched from the core
this morning and produced the most impressive thunderstorms so far
as they closed in on the USVI, Culebra, and Vieques. Frequent
lightning has been observed in these bands, with the heaviest
thunderstorm activity currently surrounding the Virgin Islands.
Most observed rainfall has occured over the local waters, however
around half an inch has been recording across the northern coast
of PR and under a tenth across the USVI. Widespread rainfall is
still expected for Puerto Rico and signs of this are appearing now
as we transition into the afternoon. Heavy rainfall is still
anticipated today over the eastern half of the region once
moisture convergence due to westerly wind flow and diurnal heating
combine. What will determine the amount of rainfall the USVI
islands receive will be the position and residency of Tropical
Storm Earl's bands over land.
.AVIATION...SHRA/TSRA expected to increase across TJSJ and the
USVI terminals through the evening hours. Outer bands of Tropical
Storm Earl will continue to affect the local area through the
overnight hours. This could cause MVFR to brief IFR conditions at
times at TJSJ/TIST/TISX. Winds from the WSW at 12-20 knots with
higher gusts thru the evening hours.
.MARINE... Hazardous marine conditions continue across the local
waters as Tropical Storm Earl continues to produce heavy
thunderstorm activity across the eastern half of the region.
Strong winds near the core of this system have resulted in the
addition of a High Surf Advisory across the northern coastline of
Puerto Rico until 6 PM today due to powerful surf recorded at the
San Juan Buoy this morning. Also the the risk of rip currents was
elevated to high for St. Croix and Culebra. Besides these
additions, all other marine hazards remain in effect.

.Previous Discussion - Issued at 340 AM AST Sun Sep 4 2022.
.SYNOPSIS...
Tropical Storm Earl is moving north of the local island today,
bringing shower and thunderstorm activity to the area. Unsettled
weather conditions will prevail for the next several days,
increasing the potential for urban and small stream flooding,
isolated flash flooding and mudslides.
&&
.SHORT TERM...Today through Tuesday...
Tropical Storm Earl now located about 90 miles northeast of St.
Thomas, USVI, at 19.5N, 64.2W. Currently, this tropical storm is
moving west-northwest at 10 mph, with maximum sustained winds of 50
mph. This system is expected to remain northeast of the local area,
but the outer bands will continue to to result in heavy rainfall
and thunderstorms across the U.S. Virgin Islands and the eastern,
northeastern, and southeastern portions of Puerto Rico during the
morning hours. By mid-morning, winds are shifting from a more west
to southwesterly flow. This means the afternoon convection is likely
to be centered over the northern-northeastern portions of Puerto
Rico and the U.S. Virgin Islands. Flooding in urban areas, small
streams, and low laying areas will be a concern for the areas
mentioned above. Mudslides are also possible in areas of steep
terrain across central interior, and the USVI. Unstable weather
conditions will continue on Monday through Tuesday. Showers
associated with the tail of Earl moving from the Caribbean, will
continue to affect the local islands. Afternoon activity is expected
to enhance the showers and thunderstorms, once again along the
central interior and northern Puerto Rico, including the San Juan
metro area. The potential threats, includes but not limited to a
risk of urban and small stream flooding, as well as mudslides in
areas of steep terrain.
&&
.LONG TERM...Wednesday through Sunday...
As Tropical Storm (or perhaps a hurricane by this time) Earl keeps
moving northward, the wind flow across the islands will remain from
the south. This will continue to pull moisture from the south,
increasing the chances of showers and thunderstorms over the area.
The showers are expected to stream from the Caribbean waters into
the southern municipalities of Puerto Rico and the U.S. Virgin
Islands through the day. In the afternoon, local effects may also
aid in the formation of convection impacting the Cordillera Central
and northern Puerto Rico, including the San Juan metro area. So far,
the GFS has this flow prevailing through Friday. Due to this
continuous moisture flux, and the previous rainfall amounts, the
risk for urban and small stream flooding, isolated flash flooding,
mudslides and rapid river rises are expected to persist. Then, by
the end of the week and through the weekend, a more seasonal flow,
out of the east late Friday and from the east during the weekend, is
expected to return. Precipitable water values are expected to remain
enhanced, however, hence this wet wetter pattern is expected to
keep going into the upcoming weekend.
Aside from the rain, this southerly flow and high humidities will
favor heat indices around 102 to 110 degrees each day, especially
before the shower activity begins or places which will not receive
so much rain.
&&
.AVIATION...
An increase of SHRA and TSRA is expected over the PR and USVI
terminals through 04/22z. The outer bands of Tropical Storm Earl
continues to affect the local area may cause brief MVFR cigs
across the all terminals. SHRA/VCTS expected for the
TJSJ/TIST/TISX terminals after 04/09Z. Afternoon TSRA/SHRA
development will result in VCTS/VCSH for TJPS 04/16-22Z and
VCTS/VCSH for TJBQ between 04/17Z. Winds from the WSW at 10 kts or
less, increasing to 10-18 knots with higher gusts after 04/14Z.
&&
.MARINE...
Hazardous marine conditions will continue today as Tropical Storm
Earl moves north of the islands. Seas up to 10 feet are expected.
As the storm moves northward, seas will improve by late tonight
and tomorrow, although small craft operators will still need to
exercise caution. Lines of thunderstorms will continue to impact
the local waters as well. For the beaches, the risk of rip
currents is high for northern Puerto Rico.
