Coastal Flood Advisory issued January 10 at 8:57PM AST until January 11 at 8:00PM AST by NWS San Juan PR

* WHAT…Life-threatening rip currents due to breaking waves
around 12-13 feet and occasionally higher, increasing to around
14-15 feet tonight into Saturday.

* WHERE…Beaches of northern Puerto Rico, from Rincon to Fajardo.
The most vulnerable areas for high surf and beach erosion
include Pinones along road 187, Parcelas Suarez, Villas del Mar,
and Villa Cristiana in Loiza; Fortuna in Luquillo; Pueblo and
Tamarindo in Aguadilla; Barrio Obrero, Pueblo and Jarealito in
Arecibo; La Boca in Barceloneta; Machuca in Manati; Puerto Nuevo
in Vega Baja; and Ocean Park in San Juan.

* WHEN…For the Coastal Flood Advisory, from midnight tonight
through 8 PM AST Saturday. For the High Surf Advisory, through 6
PM AST Sunday. For the High Risk of Rip Currents, through
Sunday afternoon.

* IMPACTS…Rip currents that can sweep even the best swimmers
away from shore into deeper water where it becomes difficult to
return to safety. 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.
Large breaking waves will result in some beach erosion with only
minor damage possible to dune structure. Shallow flooding of
vulnerable areas will result in limited threat of property and
structural damage near the waterfront and shoreline, with a
higher threat near the time of high tide. Isolated road closures
are possible.

* ADDITIONAL DETAILS…Building seas, generated by pulses of long-
period northerly swells, will promote life-threatening rip
current and dangerous swimming conditions through the weekend.
There is a high chance that the Coastal Flood Advisory may be
extended through Saturday afternoon. The next high tires are
expected as follows: In San Juan, at 7:22 AM AST at 1.75 ft and
6:07 PM AST at 0.78 ft; in Arecibo, at 6:36 AM AST at 1.97 ft
and 5:55 PM AST at 0.72 ft; in Aguadilla, 6:30 AM AST at 1.48 ft
and 5:56 PM AST at 0.51 ft; and in Fajardo, at 6:58 AM AST at
1.67 ft and 6:12 PM AST at 0.81 ft.
