Subject: Updated: Soliciting Comments on the experimental
Graphical Week Two Marine Wind Speed and Wave Height
Probabilities through November 30, 2026

Updated to extend the comment period.

Through November 30, 2026, the National Weather Services (NWS)
Ocean Prediction Center (OPC) is soliciting comments on the
experimental Graphical Week Two Marine Wind Speed and Wave
Height Probabilities. OPC produces the experimental Week Two
graphical Marine Wind Speed and Wave Height probabilities
graphics as part of the Week-Two Marine Hazards Outlook
(https://ocean.weather.gov/week2/). This webpage displays these
wind speed and wave height probabilities in percent of sustained
(one-minute average) surface (10-meter) wind speeds that are
equal to or exceeding 34 knots (kt) (39 miles per hour [mph]),
48 kt (55 mph), and 64 kt (74 mph). These values equal the
respective thresholds for gale-, storm-, and hurricane-force
winds.

In addition, the experimental graphics display probabilities in
percent of significant wave height equal to or exceeding 4
meters (m), 6m, 9m, and 14m. These probabilities are based on
the operational Global Ensemble Forecast System (GEFS),
validated and calibrated for hazardous forecast conditions. The
coverage area is from approximately 20 south latitude to 80
north latitude, and from 0 longitude to approximately 140 east
longitude. During the tropical cyclone season from June through
November, the southern extent of the coverage area will be 30
north latitude, while research continues to improve
probabilities that may include tropical systems.

Wave Height Probabilities graphics, product examples, and
requirements explanation will be found at the following link:
