Redondo Beach, WA
CATEGORY 3
WHAT
High tides are expected to peak around midday (roughly 17.8 ft) with barometric pressure near 1002–1007 hPa, creating a situation close to a flood event but unlikely to cause substantial flood damage.
WHEN
Peak tidal heights will occur around midday.
IMPACTS
Minor direct impacts to low-lying and shoreline areas are possible. While inundation is not expected to be severe, some localized ponding of water could occur near the shoreline.
• Tide heights of nearly 18 ft show some similarity to the 12/27/2023 Category 3 event, which reached 17.46 ft.
• Barometric pressure remains higher than truly severe incidents (e.g., well below 992 hPa).
• NOAA data does not list an explicit flood likelihood for 09/30, but no major flooding indicators are present.
CATEGORY 3
WHAT
A midday high tide reaching around 18.2 ft combined with moderate barometric pressure near 1014–1015 hPa suggests slightly higher water levels than Day 1 but still below thresholds typically linked to damaging floods.
WHEN
Peak tide mid-afternoon, with smaller secondary highs early morning and late evening.
IMPACTS
Minor flooding in very low-lying coastal areas is possible. However, significant property damage is not anticipated given the relatively moderate conditions.
• Tidal levels near or below 19 ft historically align with Category 3 conditions in Redondo Beach.
• NOAA’s official flood likelihood for 10/01 is 0.0%, reinforcing a low chance of widespread impacts.
• Higher barometric pressure than historical severe events further reduces the risk.
CATEGORY 3
WHAT
The highest tide of the three-day window (around 18.5 ft) occurs midday under barometric pressure near 1009–1010 hPa. Although this is the largest tide of this forecast period, it remains below the 19–20+ ft levels commonly noted in more serious flood events.
WHEN
Peak tide midday to early afternoon, with secondary highs in the early morning/evening hours.
IMPACTS
Coastal areas may see minor flooding near the shore, but significant damage is unlikely. Residents and businesses near the immediate shoreline should monitor water levels.
• NOAA’s 10/02 flood likelihood is 0.0%, supporting a lower overall flood risk.
• Compared to past Category 4 or 5 events where tides exceeded 19 ft and/or barometric pressure dropped below ~992 hPa, current conditions do not reach that severity.
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.
