A line of showers stretching from north to south crossed Puerto Rico during the afternoon hours of March 6th. This resulted in gusty straight-line wind damage across sections of eastern Puerto Rico.
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.

Area Forecast Discussion
National Weather Service San Juan PR
1003 AM AST Sun Mar 6 2022
.UPDATE...Unsettled weather conditions will continue to prevail
across the local islands throughout the day under trofiness and
plenty of moisture. Therefore, continue to expect periods of
showers with heavy rainfall as well as thunderstorms particularly
across northeast Puerto Rico and portions of central and
southwest. There is a risk of urban and small stream flooding over
these areas. Sharp rises along rivers cant be ruled out. By
Monday evening through Tuesday, moisture will decrease to seasonal
normal levels.
&&
.AVIATION...Brief periods of MVFR conds will remain possible at
the USVI terminals and JSJ/JBQ in SHRA throughout the forecast
cycle with VCTS in and around JPS through at least 06/22z. Winds
will peak up at 15 to 20 knots with stronger gusts becoming at
around 12 knots overnight.
&&
.MARINE...Fresh easterly winds and a weak northerly swell will
promote choppy and hazardous seas through at least midweek.
Boaters can expect seas up to 10 feet particularly across the
Atlantic offshore waters.

.PREV DISCUSSION... /issued 534 AM AST Sun Mar 6 2022/
SYNOPSIS...Predominately easterly surface flow and a front to the
northwest will maintain showery, cool and unstable conditions
through Tuesday. Low level moisture will persist through the end
of the week allowing shallow showers and some afternoon
thunderstorms in western Puerto Rico Wednesday through Saturday.
A high risk of rip currents will spread to most coasts today and
Monday and for northern beaches the high risk will continue
through much of the week.
SHORT TERM...Today through Tuesday...
Moisture advection under an east northeast wind flow with a frontal
boundary stalled northwest of the area has promoted a cool
advective pattern through the night hours with showers affecting
mainly the U.S. Virgin Islands and the eastern third of Puerto
Rico, including Vieques and Culebra. Although instability aloft is
present, a slight decrease in moisture at the mid-levels has
significantly reduced the thunderstorm activity across the
waters. In fact, no thunderstorms were detected throughout the
night over the forecast area. This slight reduction in moisture at
the mid-levels is expected through the morning hours. As such,
thunderstorms were removed from the forecast through late this
morning, although some very brief isolated thunderstorms cannot be
ruled out over the local waters. Regardless, scattered to
numerous showers will continue to affect windward coastal areas
through the morning hours.
The frontal boundary is not expected to move much closer to the
forecast area. However, it is anticipated that its associated
moisture will interact with a strengthening mid-level low over
the northeastern Caribbean basin and a deepening upper-level
trough today while moving eastward across the forecast area. This
will promote moisture fragmentation at the mid-levels from the
southern tip of the frontal boundary and later sinking southward
today through Monday as moisture embedded in the northeasterly
trades will continue to moisten the boundary layer. This will
support above normal moisture content up to 500 mb. This, in
combination with unstable weather conditions aloft, surface
heating, and mountain effects will produce another round of fairly
active showers and thunderstorms this afternoon. Global models
have backed off slightly from widespread thunderstorm activity
due to a slight reduction in available moisture. Nevertheless,
weather conditions still look optimal for shower and thunderstorm
activity capable of producing gusty winds and periods of moderate
to heavy rain this afternoon for interior and western sections of
Puerto Rico which will cause areas of urban and small stream
flooding. Fresh to strong wind conditions will also aid in the
formation of streamers downwind of Vieques and Culebra which could
affect the eastern municipalities of Puerto Rico and also
downwind of El Yunque into the southern sections of the San Juan
metropolitan area.
This activity is expected to persist through Sunday evening and
Monday morning with the potential of shower and thunderstorm
activity over the local waters moving over windward coastal areas,
especially over the northeastern municipalities of Puerto Rico.
Urban and small stream flooding can be expected in areas with the
heaviest showers this afternoon through early Monday morning.
Lingering moisture with instability aloft should support another
active Monday afternoon across interior and western sections of
Puerto Rico but with less coverage than today.
By Monday evening through Tuesday, moisture will decrease to
seasonal normal levels. Cloud coverage and shower activity should
decrease, but enough moisture will promote passing showers over
windward coastal areas during evening and morning hours and
localized afternoon activity mainly driven by daytime heating and
local effects across western Puerto Rico.
LONG TERM...Wednesday through Sunday...
High pressure continues across the central Atlantic through the
rest of the period to maintain 10 to 20 knot easterly surface
flow. High pressure does briefly build toward the central
tropical Atlantic to cause more east southeasterly flow over the
forecast area Friday and Saturday, but this is now showing up
weaker than in previous model runs. Nevertheless the GFS continues
to show a warming trend through Thursday and only a gradual
cooling trend afterward. Overall, the moisture pattern at low
levels remains nearly saturated and will provide ample humidity
for shower formation wherever vertical motion factors and heating
at the surface are favorable, but no significant features move
through during the period and moisture is generally less than 60
percent between 825-600 mb. This will impede vertical development
even with moderately low 500 mb temperatures through Sunday.
Moderate wind flow will also keep showers moving although some
areas could see repeated activity to the point that ponding of
water will occur--mainly in western and interior Puerto Rico.
Upper levels are marked by a ridge building into the area from the
southeast and pushing a weak jet over the forecast area Thursday
night and Friday. This passage will enhance the showers somewhat,
but this activity will tend to be modulated more by the patchy
nature of the moisture passing through Friday through Sunday.
AVIATION...Mainly VFR conds expected with VCSH over all terminals
except TJPS through 06/14Z. Brief MVFR possible for most terminals
afterwards with VCTS in and around TJPS/TJBQ through at least
06/22z. Winds picking up to around 15 to 20 knots today, remaining
out of the east, with sea breeze variations and stronger gusts.
Maximum winds WNW 30-40 kts btwn FL320-400.
MARINE...Seas at the outer buoy have begun to increase to 8 to 9
feet, but are being caused by the increasing winds to the east. A
weak spike of seas of 5 to 6 feet did make it as far south as
Rincon earlier Saturday night but they have returned to previous
levels. Seas are expected to rise with the winds and up to 10 feet
could be seen in the northern-most waters of the local Atlantic
Sunday night with 5 foot swell from the north northeast. Periods
are expected to be 8 to 10 seconds owing to the local nature of
the generation area. Seas of at least 6 feet will continue in the
local outer Atlantic waters for the rest of the week and beyond.
