    SPECIAL WEATHER STATEMENT  

Yap Coastal Waters

Special Weather Statement issued July 14 at 1:26AM ChST by NWS Tiyan GU

DEVELOPING INVEST 97W NORTHWEST OF YAP TO PROMOTE GUSTY WINDS AND CHOPPY SEAS... ...INVEST 97W TO SLOWLY LIFT NORTHWARD AWAY FROM YAP AND PALAU

Areas Affected: Koror Palau Coastal Waters; Yap Coastal Waters

Urgency: Expected

Severity: Moderate

Certainty: Observed

Alert Sent: Tuesday 1:26am ChST

Alert Effective: Tuesday 1:26am ChST

Alert Expires: Tuesday 3:00pm ChST

Event Onset: Tuesday 1:26am ChST

Issued by: NWS Tiyan GU

Details: 
...DEVELOPING INVEST 97W NORTHWEST OF YAP TO PROMOTE GUSTY WINDS AND CHOPPY SEAS... ...INVEST 97W TO SLOWLY LIFT NORTHWARD AWAY FROM YAP AND PALAU...

Latest satellite derived ocean surface wind data shows a strong burst
of west to southwest winds. These stronger winds will continue
around Yap and Palau today. Gusts up to gale force, or 35 kt, can be
expected at both Yap and Palau. Seas will build in response to the
increasing winds with hazardous conditions expected at Yap, making
inter-island travel dangerous, especially to small craft.

Regional weather continues to be dominated by the circulation, known
as 97W, which sits just northwest of Yap near 12N136E. This
circulation, still showing a broad wind field, continues to become
better organized and is now the subject of a Tropical Cyclone
Formation Alert by the Joint Typhoon Warning Center. This means that
the formation of a tropical depression is likely within 24 hours. As
97W lifts northward, winds and seas will gradually subside, first
across Palau, then across western Yap state.

Residents and mariners should keep up to date with the latest
forecasts for Yap and Palau by visiting weather.gov/gum or seeking
updated information from local weather service offices and emergency
managers.
