Prior to this, weather reports from February 3, 2026, detailed a cold front advancing across the islands, bringing cooler temperatures, gusty winds, and scattered showers, with active weather expected to persist through the weekend due to a deepening upper trough and high-pressure systems.

Overall, the week was marked by stormy weather, heavy rainfall, and hazardous marine and atmospheric conditions, gradually easing by midweek.
