Redondo Beach, WA
CATEGORY 2
WHAT
No flooding is expected. Tidal heights may reach around 18 feet, but the barometric pressure remains substantially higher than the critical low-pressure levels historically associated with flooding.
WHEN
The highest tide on August 18 is around mid-afternoon to early evening, with a secondary peak close to midnight.
IMPACTS
No coastal flooding impacts are anticipated. Normal tidal fluctuations are expected, and no road closures or inundation issues are forecast.
• Tide heights, while moderately high, are still below thresholds commonly associated with coastal flooding in Redondo Beach.
• Barometric pressures near or above 1003 hPa for peak tides significantly reduce the likelihood of flood events.
• NOAA’s flood likelihood forecast remains at 0%, indicating minimal risk.
• Compared with past flooding events, the tide and pressure values are not in the ranges that have historically caused even minor or localized flooding.
CATEGORY 2
WHAT
Again, no flooding is expected. Tide levels approach the upper teens, but barometric pressures remain well above historically low levels.
WHEN
Peak tides occur late morning and mid-afternoon.
IMPACTS
No flooding impacts are anticipated. Conditions should remain calm, and no property damage or inundation of low-lying areas is forecast.
• Maximum observed tides near 18–19 feet fall short of previous Category 3 or higher events which exceeded 20 feet and had lower pressures.
• Barometric pressures near 1007 hPa do not indicate the low-pressure systems typically linked with floods.
• NOAA continues to project a 0% chance of flooding for this date.
CATEGORY 2
WHAT
No significant risk of flooding. Tides may climb close to 19 feet in the afternoon, but with pressure readings around 1006 hPa, conditions remain well above the low-pressure trigger point.
WHEN
Highest tides are forecast in the mid-to-late afternoon on August 20.
IMPACTS
No coastal flooding issues are expected in low-lying areas or along the shoreline.
• Although the tides reach slightly higher levels (near 19 feet) than on previous days, the barometric pressure is not low enough to create a flooding scenario.
• Historical data shows that even minor to moderate flooding typically requires both higher tides (above 20 feet) and pressures nearing or below 992.8 hPa.
• NOAA’s forecast continues at a 0% flood likelihood.
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.
