Redondo Beach, WA
CATEGORY 2
WHAT
High tides near 20.17 ft are expected mid-afternoon, but the barometric pressure is notably high (around 1026 hPa), and NOAA’s Flood Likelihood is very low (1.8%). These factors together indicate no substantial risk of flooding.
WHEN
Highest tide occurs midday into early afternoon (approximately 1:00 PM – 2:00 PM PST).
IMPACTS
No flooding concerns are anticipated. Low-lying coastal spots should remain unaffected given the stable, higher-pressure system and low NOAA flood probability.
• Barometric pressure above 1025 hPa significantly reduces flood potential, even with a tide around 20 ft.
• Comparisons to historical Category 3 events showed both lower barometric pressures and higher NOAA flood likelihoods than we see here.
CATEGORY 3
WHAT
Tides are forecast to peak just above 20.2 ft, and the barometric pressure is slightly lower (around 1022–1023 hPa) compared to Day 1. While overall flooding remains unlikely, conditions approach the threshold where minor coastal impacts can occur.
WHEN
Highest risk from midday to early afternoon (roughly 1:30 PM – 2:30 PM PST), coinciding with the highest tides.
IMPACTS
Close to a flood event and worth monitoring, but unlikely to cause actual flood damage. Any impacts will likely be localized nuisance flooding along the most vulnerable low-lying shoreline areas.
• NOAA’s Flood Likelihood is still low (3.6%), but marginally higher than on 12/02.
• Tide heights are comparable to some historical moderate events, though the higher barometric pressures keep the probability of real flood damage low.
CATEGORY 3
WHAT
A similar pattern continues with tide heights around 20.1–20.2 ft and a slightly lower barometric pressure (~1020–1021 hPa). These factors put conditions close to a minor flood threshold, yet substantial flooding remains unlikely.
WHEN
Early to mid-afternoon (around 2:00 PM – 3:00 PM PST) for the highest tide. Evening tides remain high, but barometric pressure is not dropping enough to raise major concerns.
IMPACTS
Worth close monitoring in areas prone to coastal splash-over or ponding. Property damage is not anticipated; isolated low spots near the shoreline could see minor, short-lived inundation.
• Although barometric pressure is gradually lower than on prior days, it remains well above historically low-pressure readings that have accompanied more damaging flood events.
• NOAA’s Flood Likelihood (3.4%) still indicates a low overall probability of flooding.
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.
Categories 1-2: No risk of flooding.
Category 3: Close to a flood event and worth monitoring.
Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
