Redondo Beach, WA
CATEGORY 3
WHAT
On Tuesday, a relatively high tide of around 19.5 ft is expected to coincide with moderately low barometric pressure near 998.5 hPa. These combined factors bring conditions close to a flood event, though widespread damage is not anticipated based on current data.
WHEN
The highest risk period centers around midday (approximately 2:00 PM to 4:00 PM PST) when tides peak and pressure is lowest.
IMPACTS
Minor tidal overflow is possible along low-lying shorelines, docks, and roads, especially near Redondo Beach’s immediate waterfront. No major property damage is expected; however, localized ponding in vulnerable areas could briefly affect traffic.
• Compared with local historical Category 3 events, barometric pressure is not as low as in more severe floods (e.g., below ~992 hPa).
• NOAA’s flood likelihood remains at 0%, indicating a low probability of widespread impacts.
• Winds are moderate (generally below 10 mph from the south), further reducing the risk of wave-driven flooding.
CATEGORY 2
WHAT
Although another high tide near 19.5 ft is forecast in the early morning hours, barometric pressure is projected to be higher (about 1006–1022 hPa), which greatly lowers flood potential.
WHEN
Peak tide is expected before dawn (around 4:00 AM to 5:00 AM PST), after which tides gradually recede.
IMPACTS
Little to no flooding impact is expected. Low-lying areas and coastal roads may see minimal water accumulation, but conditions should remain below typical nuisance flood thresholds.
• Historically, tides under 20 ft with barometric pressure above ~1000 hPa generally do not produce notable flooding in Redondo Beach.
• NOAA’s analysis indicates a 0% flood likelihood, reinforcing the minimal risk assessment for Wednesday.
CATEGORY 2
WHAT
A similarly high tide of approximately 19.4 ft is anticipated, but very high barometric pressure near 1024 hPa reduces the chance of any flooding.
WHEN
Morning high tide peaks around 5:00 AM PST. Tides will again reach moderate levels in the late afternoon, though pressure remains elevated.
IMPACTS
No significant flooding is expected. Shoreline areas could experience minor water encroachment, but conditions should remain well below impactful flood thresholds.
• The strong barometric pressure (1024 hPa) is notably higher than pressures observed during historical flooding events.
• Wind speeds continue to be mild, providing little onshore push.
• NOAA projects a 0% flood likelihood, validating overall low flood concerns.
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.
