Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but unlikely to cause significant or dangerous flood damage. Minor coastal flooding could affect low-lying areas along the shoreline.
WHEN
Greatest risk near the evening high tide, approximately 8:00 PM to 9:00 PM on May 16, when tides reach around 19.19 ft.
IMPACTS
• Minor flooding of low-lying areas and beaches.
• Possible isolated ponding on roads near the waterfront.
• No major property damage expected.
The highest tide on May 16 is forecast at around 8:42 PM, reaching approximately 19.19 ft with a barometric pressure near 1002.51 hPa. While the pressure is somewhat low relative to typical fair-weather readings, it is not near the historically significant 992.8 hPa threshold. Compared to similar historical Category 3 events, these conditions suggest localized but not severe flooding concerns.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. Minor coastal flooding may occur, but widespread or severe damage is not anticipated.
WHEN
Peak risk late in the evening on May 17, near 9:00 PM to 10:00 PM, when tides are expected to be just under 19.2 ft.
IMPACTS
• Minor flooding in typically vulnerable low-lying areas.
• Possible brief impacts to roads closest to the shoreline.
Although barometric pressure readings (around 998–999.5 hPa) are a bit lower than on May 16, the tide height remains below historically high flood levels. Historical Category 4 events generally involve either higher tide levels or significantly lower pressure. Consequently, conditions remain consistent with a Category 3 rating, indicating limited flooding potential.
CATEGORY 4
WHAT
Flooding is likely, although not expected to result in major property damage. Low barometric pressure near 992.44 hPa coinciding with higher water levels increases the overall flood risk.
WHEN
Greatest threat around late evening on May 18, near 9:00 PM to 10:00 PM, when tides are forecast to peak close to 19.0 ft.
IMPACTS
• Standing water and flooding possible in low-lying coastal areas.
• Minor to moderate issues on roads near the shoreline, potentially leading to short-term closures.
• Property damage is generally not expected to be widespread or severe.
The barometric pressure on May 18 is predicted to drop close to 992.44 hPa, aligning with past events that have produced more noticeable flooding. Even though the projected tide height (about 19 ft) does not exceed 21 ft, the notably low pressure can still elevate the flood risk to Category 4, similar to past moderate coastal flooding events (e.g., 01/07/2022).
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.
