Day 1: 2026-09-16

Category 1

WHAT
A routine day with no flood risk. Tides are moderate, and pressure is slightly above low-flood thresholds, keeping conditions stable for the morning and evening high tides.

WHEN
Highest tidal levels around mid-morning near 9:54 AM and again in the evening around 8:30 PM.

IMPACTS
- No impact anticipated.

REASONING
The tide was the primary contributing factor, with minor supportive influence from pressure. Wind had little to no effect. This is similar to the 2023-11-10 Cat 1 event.


Day 2: 2026-09-17

Category 1

WHAT
Another routine day with no sign of flooding. Although pressure is slightly lower than the previous day, it remains well above levels that would cause concern.

WHEN
Peak tides around late morning near 11:00 AM and again in the evening close to 9:12 PM.

IMPACTS
- No impact anticipated.

REASONING
Tide and slightly below-normal pressure provided a small positive contribution, but overall levels stay well within safe margins. Wind contributed minimally. Similar conditions have been seen on past Cat 1 days, such as 2024-10-11.


Day 3: 2026-09-18

Category 1

WHAT
No flood risk is expected. The combination of moderate tides and moderate pressure keeps water levels comfortably below flood thresholds.

WHEN
High tides occur around early afternoon near 12:30 PM and again in the late evening near 10:06 PM.

IMPACTS
- No impact anticipated.

REASONING
