Redondo Beach, WA
CATEGORY 2
WHAT
No flood risk is anticipated. Tides are expected to reach moderate levels (around 16 ft to 18 ft), but barometric pressure remains well above the critical low threshold (~992.8 hPa). NOAA’s official forecast indicates a 0.0% flood likelihood.
WHEN
Highest tide periods on 2025-04-20 occur near 08:18 and again late afternoon, but both coincide with relatively stable atmospheric pressure (above 1003 hPa).
IMPACTS
No significant impacts to property or major roadways are expected. Low-lying areas should remain unaffected.
• Compared with the Category 3 event of 12/27/2023 (17.46 ft, lower pressure), current barometric pressures are higher, and NOAA reports no flooding likelihood.
• Wind speed is low, further reducing the potential for coastal surge.
• The tidal heights are below those of historical Category 4 and 5 events, and pressure is not low enough to raise concerns.
CATEGORY 2
WHAT
No flood risk is expected. Tides remain moderate (peaking around the midday/afternoon), and atmospheric pressure readings (around 1006–1010 hPa) continue to remain well above flood-trigger levels.
WHEN
Highest tide for 2025-04-21 is near 15:18 with a mean sea-level pressure of about 1010.35 hPa.
IMPACTS
No inundation of normally dry areas. Minimal effect on shorelines or roads.
• NOAA’s flood likelihood remains at 0.0%, with a comfortable margin below the flood threshold.
• Even though the tide is in a similar range to past Category 3 events, the persistent higher barometric pressure and NOAA’s low-flood assessment point to reduced risk.
CATEGORY 2
WHAT
No flood risk is projected. Although a nighttime high tide near 00:54 could briefly approach 18.5 ft, barometric pressure is still above 1004 hPa, which is high compared to historic flooding events. NOAA forecasts 0.0% likelihood of flooding.
WHEN
Key tide times include around 00:54 and 19:36, both paired with relatively stable barometric pressures (1011 hPa and ~1004 hPa, respectively).
IMPACTS
No noticeable coastal flooding. Beaches and low-lying roads remain clear.
• These tide levels are below the 19–20+ ft range often observed for higher-category events.
• The barometric pressure is considerably higher than in historical severe flood events, such as 12/27/2022 (Category 5) with ~978 hPa.
• NOAA’s analysis consistently indicates no impending flood threat.
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.
