Redondo Beach, WA
CATEGORY 3
WHAT
High tides on August 5th are expected to reach approximately 18.5 ft. Barometric pressure readings near 1002 hPa are moderately low, but not low enough to indicate a severe event. NOAA’s Flood Likelihood is 0.0%, suggesting minimal flood probability. Overall conditions warrant monitoring, but damaging coastal flooding is unlikely.
WHEN
Peak tides occur around mid-to-late afternoon on August 5th (roughly 3 PM – 5 PM local time).
IMPACTS
Minor water inundation near coastal edges is possible but not expected to cause notable property damage. No widespread road closures or severe impacts are anticipated.
• Although tide levels are above 17 ft (historically associated with Category 3 events), pressure is not nearly as low as in significant flood events (<992 hPa).
• Winds are light (around 5–10 mph), mainly from the S/SSW, reducing onshore surge potential.
• Historical comparisons (e.g., 12/27/2023, Category 3 with lower tide and slightly higher pressure) suggest a similar or slightly higher water level, but NOAA’s analysis indicates minimal risk.
CATEGORY 3
WHAT
Tide forecasts indicate levels of about 18.8 ft. Barometric pressure is projected at about 1006.5 hPa during the afternoon peak. This combination places conditions just below more significant thresholds and aligns with a Category 3 (close to flood event) scenario.
WHEN
Highest tides are expected mid to late afternoon on August 6th (roughly 3 PM – 5 PM local time).
IMPACTS
Localized ponding in the lowest-lying coastal spots is possible, but damaging flooding is not anticipated. Most residents and infrastructure should see minimal if any impacts.
• Despite the relatively high tide, the barometric pressure remains well above critical low-pressure thresholds.
• NOAA’s Flood Likelihood remains at 0%.
• Historical moderate flooding (Category 4) typically involved even higher tides (>19 ft) and/or substantially lower barometric pressure or stronger winds.
CATEGORY 3
WHAT
Tides near 19.0 ft are forecast for the afternoon of August 7th, with barometric pressure around 1004.5 hPa. This tide height compares to past Category 3–4 thresholds; however, the absence of very low pressure or high winds reduces the risk of damaging floods.
WHEN
Peak water levels occur mid-to-late afternoon on August 7th (around 3 PM – 5 PM local time).
IMPACTS
Minor flooding in low-lying areas is possible. Routine cautions may be considered for shore-adjacent properties, but no significant property damage is likely.
• Although slightly higher than Day 1 and Day 2, pressure remains above historically established severe-flood benchmarks (~992 hPa).
• NOAA’s Flood Likelihood (0%) supports minimal flood risk.
• Winds are generally light and not from a direction (W/NW) that would greatly enhance tide-driven surges.
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.
