Redondo Beach, WA
CATEGORY 3
WHAT
Elevated high tides around 20 ft combined with moderately low barometric pressure (near 995 hPa early and dipping below 992.8 hPa later in the evening) may lead to water levels close to minor flooding thresholds. Overall, no major impacts are expected, but conditions are worth monitoring.
WHEN
Primary concern near the morning high tide (around 07:06 AM) and again near the evening high tide (around 07:00 PM to 08:00 PM).
IMPACTS
• Minor ponding of water possible in very low-lying coastal spots.
• No significant property damage anticipated.
• Brief, isolated overflow near shorelines cannot be ruled out.
Comparing to historical events:
• The highest observed tide ~20 ft is below the ~21 ft typically associated with more serious flooding.
• Barometric pressure is near flood-watch levels but not definitively low enough to drive a major event.
• NOAA flood likelihood is only around 1.0%, consistent with a limited threat.
CATEGORY 2
WHAT
Morning high tide may again approach 20 ft, but barometric pressure is above extremely low thresholds and NOAA indicates a minimal flood likelihood (0.2%). Conditions do not warrant flooding concerns.
WHEN
High tide of note around 07:36 AM, but no significant ocean overflow is expected.
IMPACTS
• No notable flooding impacts anticipated.
• Historically, tides of around 20 ft can raise concern if pressures drop, but Day 2’s barometric pressure remains relatively higher (near 996 hPa at peak tide).
• NOAA’s 0.2% flood likelihood further confirms no real flood threat.
CATEGORY 2
WHAT
Peak tide near 19.7 ft and higher barometric pressure (over 1015 hPa). NOAA’s forecast calls for negligible (0.0%) flood likelihood.
WHEN
Highest tide mid-morning (~08:12 AM) and a secondary high tide late evening (~10:30 PM), but both well below critical flood conditions.
IMPACTS
• No risk of coastal flooding.
• Even though the tidal heights surpass 16 ft, the relatively high pressure and low wind speeds dramatically reduce any flooding potential.
• No correlation with known severe-flood criteria (>21 ft tide plus low barometric pressure).
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.
