Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected on this day. Although the midday tide is forecast to approach approximately 18.2 feet, the barometric pressure remains above 1010 hPa, and NOAA’s Flood Likelihood indicates a 0% chance of flooding.
WHEN
Highest tide near midday (around 1:30 PM to 2:00 PM local time).
IMPACTS
• No significant coastal inundation expected.
• Shoreline areas should remain largely unaffected.
Based on comparisons with historical events, a tide height near 18 feet alone has not historically caused flooding unless paired with significantly lower atmospheric pressure (< 1000 hPa). Current barometric pressure forecasts above 1010 hPa reduce the risk. NOAA’s official likelihood remains very low (-2.95 m to threshold), supporting Category 2 (no risk).
CATEGORY 2
WHAT
No risk of flooding is expected on this date as well. Projected maximum tide of roughly 18.5 feet is not accompanied by low barometric pressure, and NOAA’s Flood Likelihood remains at 0%.
WHEN
Peak tide around mid-afternoon (1:30 PM – 2:30 PM local time).
IMPACTS
• Minimal to no flooding concerns.
• Normal beach and shoreline activity expected.
Although tide levels briefly approach the upper teens in feet, barometric pressure near or above 1014 hPa, along with calm winds, indicates minimal risk. Historical Category 3 events typically involve a notable drop in barometric pressure or tides exceeding 20 feet. NOAA’s distance to tidal flood threshold (-2.65 m) clearly shows no immediate threat.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but unlikely to cause flood damage. Tides may reach around 18.8 feet, with barometric pressure dipping to near 1006 hPa—somewhat lower than on previous days.
WHEN
Peak tide expected early to mid-afternoon (about 2:30 PM local).
IMPACTS
• Minor caution near shorelines and moat-like flooding in very low-lying areas is possible but not likely to cause significant damage.
• Vigilance is advised due to the moderately higher tide levels compared to Days 1 and 2.
Historically, a Category 3 event (e.g., 12/27/2023, 17.46 ft tide at ~1006 hPa) did not result in major damage. Here, the slightly higher tide (~18.8 ft) with a similar pressure warrants monitoring but is still unlikely to produce widespread flooding, particularly as NOAA’s official likelihood remains 0% (-2.35 m to threshold). This status justifies Category 3 as a precautionary note.
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.
