Day 1: 2026-09-11

CATEGORY 2

WHEN Peak water levels are expected in the early evening around 6:06 PM.

IMPACTS • No impact anticipated.

Day 2: 2026-09-12

CATEGORY 2

WHAT Category 2 indicates routine conditions without notable flood risk. Moderately high tides combined with slightly lower pressure do not appear sufficient to cause flooding.

WHEN Peak tide and minor risk toward the evening, near 6:36 PM.

IMPACTS • No impact anticipated.

REASONING The high tide was the principal factor in this classification, with minor contribution from slightly below normal pressure. Onshore wind made little difference. This is similar to the 2023-01-06 Cat 3 event, though current conditions are at a lower Category 2.

Day 3: 2026-09-13

CATEGORY 2

WHAT Category 2 again signals no flooding risk. A moderately high tide and modestly lower pressure keep us in a routine state.

WHEN Highest tide is expected in the evening near 7:00 PM.

IMPACTS • No impact anticipated.

REASONING Tide height was the primary driver, while slightly below normal pressure provided minor support. Onshore wind remained minimal. This is similar to the 2023-01-06 Cat 3 event, but the forecast settles at Category 2.
