Harbor Surge Forecast

Harbor Surge Forecast

A new overlay has been added to Voyager’s “hazards” category: a harbor surge forecast for Haleʻiwa Harbor on the North Shore of Oʻahu in Hawaiʻi. Forecasts for other harbors are planned for the future—Barbers Point is in development. Clicking on the map icon produces a pop-up window with a time series plot of the most recently available observed and predicted conditions. This overlay complements the high sea level and wave run-up forecasts that we announced earlier in February.

Harbor surge forecasts provide advance notice of potentially dangerous surge currents within harbors. These forecasts can alert locations up to six days in advance if the surge current will be at or above a pre-determined threshold of extreme activity. When this threshold is exceeded, damage to boats and infrastructure may occur due to the jostling of boats and floating docks, and safe navigation becomes problematic.
