Possible Impacts
Saharan Dust concentrations are forecast to remain low through the next seven days.
From Friday, October 27th, 2023, spring tides are forecast to begin and continue through November 4th, 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, from Friday, October 27th, 2023, through Monday, October 31st, 2023, long-period swells are forecast to affect mainly the northern coastlines of both islands, increasing both the threat of rip currents and beach erosion, with the possibility of minor coastal flooding during high tide periods.
