Redondo Beach, WA
CATEGORY 3
WHAT
Tides early on March 10 are expected to reach approximately 19.4 ft around 03:42 PST with a barometric pressure near 1004.7 hPa. These conditions approach flooding thresholds but are unlikely to cause significant property damage.
WHEN
Highest concern near the early morning high tide window (roughly 02:30–04:30 PST on March 10).
IMPACTS
• Some low-lying coastal spots may see minor water inundation.
• Very localized pooling on roads close to the waterfront.
• Barometric pressure is not especially low compared to past severe events.
• NOAA’s official flood likelihood is listed as 0.0% for this date, which supports a relatively modest flood risk.
• Historically, tides above 20 ft and pressures below ~992 hPa have led to more serious issues. These Day 1 forecasts are below those thresholds.
CATEGORY 3
WHAT
A high tide near 19.5 ft around 04:12 PST comes with moderate barometric pressure (~1007.9 hPa). A second, lower high tide near 17 ft in the afternoon lines up with a lower pressure (~999.2 hPa). Overall, conditions are still close to a flood event but, as with Day 1, not quite severe enough to suggest major property damage.
WHEN
• Main high tide risk in the early morning (roughly 03:00–05:00 PST on March 11).
• A secondary period of moderate concern in mid-afternoon (roughly 13:00–15:00 PST) when pressure dips further but tide height remains a bit lower.
IMPACTS
• Possible water intrusion into low-lying areas or beachfront parking lots.
• Nuisance-level ponding on roads nearest the coast.
• Even with the lower barometric pressure during the afternoon tide, the water level itself (about 17 ft) remains below the more critical flood levels observed in Category 4 events.
• Wind speeds are not forecast to be as high as in historical severe flood situations, further reducing overall risk.
• NOAA’s official flood likelihood remains at 0.0%, indicating minimal danger of a significant flood event.
CATEGORY 3
WHAT
Morning tides are predicted to peak around 19.5 ft (04:36 PST) with barometric pressure near 1005.5 hPa. While this is again fairly high water, it remains just below historically more damaging tide thresholds.
WHEN
• Main concern in the early morning (roughly 03:30–05:30 PST on March 12).
• Evening tides are much lower (around 9–10 ft), and barometric pressure is not forecast to be dangerously low.
IMPACTS
• Minor inundation may occur in the most vulnerable shoreline spots.
• Limited roadway impacts, generally confined to immediate waterfront areas.
• Despite the moderate tide heights, barometric pressure is not forecast to drop near critical lows (~992 hPa) that significantly compound flood risk.
• NOAA’s flood likelihood data remains at 0.0%, aligning with only modest localized flooding concerns.
• Compared with historical Category 4 or 5 events—where tides exceeded ~20 ft with substantively lower pressure—these Day 3 conditions stay in a less severe range.
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.
