Redondo Beach, WA
CATEGORY 2
WHAT
No flooding is expected on Day 1. Tides will reach around 19.4 ft in the early morning hours, which is below the approximate 21 ft threshold tied to flood events in this area. Barometric pressure near high tide (around 1008.88 hPa) is higher than the low-pressure levels historically associated with coastal flooding.
WHEN
• Primary high tide of interest near 04:36 AM PST.
• Secondary (evening) high tide near 08:30 PM PST (with even higher pressure ~1022 hPa).
IMPACTS
No significant impacts are anticipated. Low-lying areas are unlikely to experience coastal inundation, and roads should remain fully open based on both observed barometric pressure and NOAA’s 0% flood likelihood forecast.
• Historically, higher-risk coastal floods in Redondo Beach involved tides exceeding 20 ft alongside notably lower barometric pressure (< 1000 hPa).
• Today’s barometric pressure around 1008–1022 hPa remains safely above that low-pressure benchmark.
• NOAA’s official Flood Likelihood for 2025-03-12 is listed as 0.0%.
CATEGORY 2
WHAT
No flooding is expected on Day 2. Peak tides approach about 19.4 ft in the early morning hours, still below the critical level needed to cause inundation in the absence of low barometric pressure. Measured pressure near high tide is 1024 hPa or higher, which further reduces the flood threat.
WHEN
• Main high tide of interest near 05:00 AM PST.
• Another moderate high tide around mid-afternoon (16:24 PST) but at a lower level (~17.6 ft).
IMPACTS
No substantial coastal flooding is anticipated. Minor ponding in the usual low spots is possible but is not expected to affect property or necessitate closures.
• Comparing with past Category 3 or 4 events shows significantly lower barometric pressure was a factor then. By contrast, today’s readings hover well above 992–1002 hPa.
• NOAA’s Flood Likelihood for 2025-03-13 remains at 0.0%, supporting a “no flood” forecast.
CATEGORY 2
WHAT
No flooding expected on Day 3. Although tides again reach nearly 19.3 ft around dawn, the pressure measured near high tide (~1033 hPa) indicates stable conditions, well above the critical low-pressure threshold associated with most flood events here.
WHEN
• Highest tide of the day near 05:12 AM PST (about 19.3 ft).
• Evening high tide near 17:06 PST (~17.8 ft).
IMPACTS
Minimal impacts foreseen in coastal or low-lying areas. Roads and property are not at risk given the current stable weather pattern and no indication of flooding from NOAA.
• Historically, Category 3 or higher events require either a tide in excess of ~20–21 ft or a substantially lower barometric pressure near 992–1002 hPa. Neither condition is present.
• NOAA Flood Likelihood for 2025-03-14 is also at 0.0%.
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.
