231

Guam – The National Weather service has issued a High Surf Advisory for the Marianas which will took effect Monday at 6 pm.

 The NWS says the cause of the high surf  are strong winds which occurred a few days ago south of Japan and produced swells over the northwest Pacific.

Those swells will move into the Marianas by this evening and generate hazardous surf  through Wednesday morning at 6 am when the High Surf Advisory expires.

The High Surf will effect north facing reefs:

* Expect surf of 7 to 9 feet by Monday evening through Wednesday morning

 Precautionary/Preparedness actions

Avoid venturing near exposed reefs and beaches, especially those along north facing reefs as rip currents are life threatening.

In addition,  the National Weather Service has also issued a Small Craft Advisory for the waters around Guam which begins this evening [Monday] and lasts through Wednesday morning.

The NWS says large swells entering the area combined with wind generated waves will cause sea heights to increase from 6 to 8 feet today to between 9 and 10 feet by this evening.

The Small Craft Advisory takes effect at 6 pm this evening and will last until 6 am Wednesday.

If navigation is unavoidable, exercise caution, especially when entering or leaving harbors and inlets…and near reef lines. Wear flotation gear.
