Possible Impacts
Saharan Dust concentrations are forecast to increase gradually through the forecast period but are not expected to significantly affect visibility.
Spring tides are forecast through November 1st, 2023. These higher-than-usual high tides and lower-than-usual low tides will require extra caution from mariners, particularly during high tide periods. Additionally, through Monday, October 31st, 2023, long-period swells are forecast to affect mainly the northern coastlines of both islands, increasing the threat of rip currents and beach erosion, with the possibility of minor coastal flooding during high tide periods.
