Redondo Beach, WA
CATEGORY 3
WHAT
Moderate high tides near 18.4 ft are expected later in the evening, coupled with barometric pressure around 1012 hPa. NOAA’s data shows a 0% flood likelihood, indicating that while tides are high enough to warrant attention, actual flooding is unlikely.
WHEN
Highest tidal levels from approximately late evening into the early overnight hours of 8/17.
IMPACTS
No significant flooding is anticipated. However, very low-lying areas near the shoreline could experience brief minor ponding.
• Tides are higher than the historical Category 1-2 events but remain below the threshold typically associated with severe flooding.
• Barometric pressure is not notably low (far from the 992 hPa or lower range seen in several historical flood events).
• NOAA’s Flood Likelihood remains at 0%, further suggesting minimal-to-no flood impact.
CATEGORY 3
WHAT
Projected tide heights of about 17.7 ft combined with barometric pressure near 1003 hPa. Again, NOAA’s forecast indicates a 0% flood likelihood. These factors place conditions close to, but not over, typical minor flood thresholds.
WHEN
Mainly around the morning and late-night high tides (08:48 and 23:48).
IMPACTS
Though unlikely to cause flooding, water may approach the edges of low-lying areas. Residents should be aware of possible minor shoreline impacts during the peak tide windows.
• While the barometric pressure is somewhat lower than Day 1’s, it remains higher than the critical thresholds observed in major flood events.
• Historical Category 3 examples showed similar or slightly lower tide levels, but often had corresponding NOAA flood-likelihood percentages above zero. Here the likelihood is still 0%, mitigating significant flood concerns.
CATEGORY 3
WHAT
Tides may peak near 18.9 ft midday (around 15:36), with barometric pressure around 1001 hPa. Although lower pressure can heighten concern, NOAA still reports a 0% flood likelihood.
WHEN
Late morning to mid-afternoon high tide (approximately 09:54 to 15:36).
IMPACTS
Conditions warrant monitoring but remain unlikely to cause damaging flooding. Extremely low-lying or poorly drained waterfront spots may see limited water encroachment.
• Compared to historical Category 4/5 events, forecasted tides are lower than the 19.25–22+ ft levels that caused noticeable property damage.
• The barometric pressure, while on the lower end for the period, does not approach the significantly low levels (near or below 992 hPa) strongly correlated with severe surges.
• NOAA’s 0% flood likelihood rating further supports that widespread flooding is not expected.
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.
