Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected on March 19. Tide levels will be elevated (peaking near 19.6 ft early in the morning), but the barometric pressure of approximately 1011.7 hPa is not particularly low, and NOAA’s flooding likelihood forecast is at or near 0%.
WHEN
Highest tide around 04:54–05:00 PST.
IMPACTS
No notable coastal flooding impacts are anticipated. Low-lying and shoreline areas should remain unaffected given these conditions.
• Compared to higher-category historical events (e.g., Cat 4–5, which had lower barometric pressure and tides often exceeding 20 ft), the barometric pressure for March 19 is relatively higher, relieving concern of significant storm surge.
• NOAA flood likelihood models also indicate essentially no probability (<0.1%) of flooding.
CATEGORY 2
WHAT
Again, no risk of flooding is expected. Although tide heights will approach 19.8 ft, the barometric pressure remains fairly high (around 1016.9 hPa), and NOAA’s flood likelihood forecast is below 1%.
WHEN
Potentially highest tide during the early morning (around 05:18–05:48 PST) and another evening tide near 18:06 PST.
IMPACTS
No concerns noted for property damage or inundation. Coastal areas should remain stable under these conditions.
• Historically, Category 3 or higher events usually involve more significant factors such as pressure dipping below ~1006 hPa or tides surpassing 20–21 ft. Neither appears to be present on March 20.
• With light winds (not specified as significant) and generally moderate weather conditions, the tide alone is unlikely to cause any appreciable flooding.
CATEGORY 2
WHAT
No risk of flooding is expected for March 21. Forecast tide levels hover around 19.8 ft, but barometric pressure near 1013.5 hPa and NOAA’s 0.1% flood likelihood indicate minimal cause for concern.
WHEN
Morning high tide approaching 05:48 PST and another peak around 19:00 PST.
IMPACTS
No notable impact to roads or property; low-lying coastal areas should see typical, non-flood tidal influence.
• Even with a relatively high tide, the higher barometric pressure and lack of strong onshore winds reduce storm surge risk significantly.
• Compared to the severe 12/27/2022 Category 5 event (which involved tide heights above 22 ft and very low pressure around 978 hPa), these conditions are far less conducive to 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.
