Category 2 · NO FLOODING EXPECTED

Flood Watch

Redondo Beach, WA

Day 1: 2026-05-16

CATEGORY 2

WHAT
Category 2 conditions are expected, mainly driven by a moderately high astronomic tide combined with a king tide bump. Barometric pressure remains near normal, and onshore winds are minimal.

WHEN
Peak water levels will occur in the early morning around 4:00–4:06 AM and again in the early evening around 6:00–6:06 PM.

IMPACTS
• No impact anticipated.

REASONING
Tidal height is the primary factor, with an added boost from the king tide. Pressure is slightly above low-flooding thresholds, and wind contributes little. A similar day on 2025-12-05 reached Category 3, but lower overall conditions now yield Category 2.

Day 2: 2026-05-17

CATEGORY 2

WHAT
Another day of Category 2 conditions, with moderately high tides shaping the forecast. Pressure is notably higher than any concerning thresholds, and winds remain very light.

WHEN
Main high tides arrive around 4:42 AM and 7:18 PM.

IMPACTS
• No impact anticipated.

REASONING
The tide is once again the main contributor, but strong high-pressure readings and minimal onshore flow keep the risk low. Although a past analog day (2025-01-06) reached Category 3, conditions this time are less elevated, resulting in Category 2.

Day 3: 2026-05-18

CATEGORY 2

WHAT
Category 2 conditions persist, largely from a continued moderate tidal influence. Pressure remains near or slightly above normal, and onshore winds are negligible.

WHEN
Highest water levels are expected in the early morning around 5:24 AM and then again in the evening near 8:12 PM.

IMPACTS
• No impact anticipated.

REASONING
Moderate tides continue to be the main driver, with above-average pressure and very minimal winds limiting any flood threat. One of the closest analogs (2025-01-06) was Category 3, but conditions now are lower, aligning with Category 2.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
