Redondo Beach, WA
CATEGORY 3
WHAT
Tides are expected to reach near 19.4 ft during the late evening, with moderately low barometric pressure around 1004 hPa. This places conditions close to a flood event; however, significant damage is unlikely.
WHEN
The highest tide is forecast around 22:42 local time.
IMPACTS
Minor coastal flooding could occur in very low-lying areas, but most properties and infrastructure are expected to remain safe. Road spray or brief ponding may be possible along the immediate shoreline.
• The barometric pressure is not near 992.8 hPa, reducing the likelihood of major flood impacts.
• Historical Category 3 events have shown tides in the 17–20 ft range with varying pressure. Today’s values are within that band, but the pressure is sufficiently high to limit severe flooding.
CATEGORY 3
WHAT
Tides approaching roughly 19.8 ft are expected around midnight, accompanied by barometric pressure near 1003.6 hPa. Conditions will be monitored closely, but widespread flooding is not anticipated.
WHEN
The highest tide is forecast near 23:18 local time.
IMPACTS
Low-lying coastal spots and roads immediately next to shorelines may see minor flooding, though major issues are not expected. Access roads or parking areas closest to the water could briefly experience standing water.
• The barometric pressure remains above more critical historical thresholds, keeping flood risk in check.
• Although this tide is slightly higher than Day 1, it remains below the levels observed in past Category 4 events.
CATEGORY 3
WHAT
Peak tide heights will be lower than on previous days (roughly 16 ft mid-day), but barometric pressure is a bit lower (around 1000–1001 hPa). Despite being near a flood threshold, significant damage is unlikely.
WHEN
The most notable tide periods occur in the morning through early afternoon hours.
IMPACTS
Minor wiring or ponding in especially low-lying areas is possible, primarily where the shoreline is already vulnerable. Most residential and commercial areas are unlikely to experience notable flooding.
• Historically, tide heights around 17 ft have sometimes triggered Category 3 events. Although today’s tide is slightly lower, the somewhat decreasing pressure keeps conditions near the threshold.
• No flood-risk data from NOAA CO-OPS is available for these dates to refine the forecast, so this category is based solely on tide and pressure patterns compared with past events.
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.
