...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Fresh winds and rough seas associated with the outer periphery
of Tropical Storm Norbert are affecting the outer offshores of
the tip of Baja California Sur. Fresh to strong N gap winds
continue across the Tehuantepec region and downwind to near 14N.
Moderate to locally rough seas are with these winds. Light to
gentle winds dominate the offshore waters of Baja California
under the influence of a weak ridge centered near 27N124W.
Light to gentle winds and moderate seas are present elsewhere
across the remaining Mexican offshore waters.
For the forecast, Norbert will move to 16.6N 119.9W this
afternoon, 16.7N 122.5W Fri morning, 16.7N 124.8W Fri afternoon,
16.9N 126.9W Sat morning, 17.3N 128.9W Sat afternoon, and 17.8N
130.4W Sun morning. Norbert will strengthen to a hurricane over
18.5N 133.5W early Mon. A trailing tropical wave is forecast to
provide mainly moderate to fresh SE winds to the SW Mexican
offshore waters through today. Otherwise, fresh to strong N to NE
gap winds will continue to pulse across the Gulf of Tehuantepec
through early Fri.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Fresh to strong northeast to east winds are blowing in the Papagayo
region and downwind to 90W, with moderate to rough. Gentle to
moderate SE to S winds are across the offshores between Ecuador
and the Galapagos Islands along with moderate seas. Otherwise,
moderate or weaker winds with slight to moderate seas prevail
elsewhere.
For the forecast, high pressure north of the area will support
fresh to strong easterly winds, and moderate to rough seas across
the Gulf of Papagayo region through Fri, then mainly moderate to
fresh winds and moderate seas are expected. Meanwhile, moderate
to fresh southerly winds are expected over the waters between
Ecuador and the Galapagos through tonight, then diminishing some
afterward. Moderate or lighter winds and moderate seas in long
period SW swell are forecast elsewhere.
