...HIGH RIP CURRENT RISK IN EFFECT FROM SATURDAY MORNING THROUGH
LATE SUNDAY NIGHT...
* WHAT...Large breaking waves up to 7-13 feet resulting in
dangerous swimming conditions and minor beach erosion.
* WHERE...The most vulnerable areas for high surf and beach
erosion include Pinones along Road 187, Parcelas Suarez, Villas
del Mar, and Villa Christiana in Loiza; Fortuna in Luquillo;
Pueblo and Tamarindo in Aguadilla; Barrio Obrero, Pueblo and
Jareaito in Arecibo; Las Boca in Barceloneta; Machuca in Manati;
Puerto Nuevo in Vega Baja; Ocean Park in San Juan; and Barrio

* WHEN...For the High Surf Advisory from 8 AM saturday to 6 AM
AST monday. For the High Rip Current Risk from saturday
morning through late sunday night
* IMPACTS...For the High Surf Advisory, High waves that can wash
over jetties and sweep people and pets onto jagged rocks.
Rough surf may also knock you down. Large breaking waves will
result in localized beach/dune structure erosion and dangerous
swimming conditions. For the High Rip Current Risk, rip
currents can sweep even the best swimmers away from shore into
deeper water, where it becomes difficult to return to safety.
* ADDITIONAL DETAILS...Erin will be generating thunderstorms over
the regional waters resulting in the potential for heavy rain,
frequent lightning and gusty wind conditions across coastal
areas.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing localized beach erosion and
dangerous swimming conditions.
There is a high risk of rip currents.
Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards, beach patrol flags and
signs.
If you become caught in a rip current, yell for help. Remain
calm, do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current, swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.

This Hazardous Weather Outlook is for portions of Puerto Rico.
.DAY ONE...Today and Tonight
.Lightning...Isolated thunderstorms, particularly across the
interior and western PR in the afternoon, across the rest of the
region late tonight. Stay alert and be prepared to take shelter
if storms develop.
.Excessive Rainfall...Flooding in urban areas, roads, small
streams, and washes, particularly across western PR. There is a
low chance of isolated flash floods. Elsewhere, plan for water
ponding on roads and in poorly drained areas.
.Excessive Heat...This level of heat affects primarily those
individuals extremely sensitive to heat, especially when outdoors
without effective cooling and/or adequate hydration. These
conditions are most likely across the urban and coastal locations.
.Marine Conditions...Hazardous conditions for small craft in
areas with seas of 7 feet or higher, particularly across
the Atlantic Offshore waters. Small craft should exercise caution
elsewhere across the local waters.
.Rip Currents...Life-threatening rip currents are possible in the
surf zone, particularly across the north and east-facing beaches.
Isolated stronger rip currents may occur elsewhere, especially
near piers, jetties, and channels.
.DAYS TWO THROUGH SEVEN...Saturday through Thursday
Erin is forecast to move northeast of the region during the
weekend, when its external bands will deteriorate local weather.
The main hazard associated with it are hazardous marine and
coastal conditions, excessive flooding rains and gusty winds.
Stay informed and monitor future forecasts. Another tropical
wave will move near the islands by the middle of next week.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is encouraged. Please relay any information
about flooding, winds, waves, and rip currents to the National
