Redondo Beach, WA
CATEGORY 3
WHAT
Tides will peak near 17.0 ft in the early afternoon with moderately low barometric pressure around 1001 hPa. This places conditions close to a flood event and worth monitoring, though significant flooding or property damage is not expected.
WHEN
The highest tide is expected around mid-afternoon on 6/21.
IMPACTS
• Minor inundation of very low-lying areas near the shore could occur.
• Minimal impacts to property and infrastructure are anticipated.
Comparing to the 12/27/2023 Category 3 flood event (tide ~17.460 ft, pressure ~1006.1 hPa), Day 1’s projected tide is slightly lower, but the barometric pressure is somewhat lower (1001 hPa). Overall, the risk profile remains in line with Category 3 conditions.
CATEGORY 3
WHAT
A high tide of approximately 19.7 ft is expected overnight into early morning, with barometric pressure in the 1002 hPa range. This tide height is notable but still below the levels commonly associated with significant coastal flooding.
WHEN
Peak tide near 00:36 on 6/22, with secondary high tide mid-afternoon.
IMPACTS
• Occasional minor flooding in very low-lying coastal areas possible.
• Property damage is unlikely.
Although the tide approaches 20 ft, the barometric pressure is not near or below the very low historical thresholds (around or below 992.8 hPa) that typically lead to more serious flooding. Historical events with similar or slightly higher tide heights but lower pressure have been categorized at 4 or above; here, the moderately low (but not extreme) pressure and light winds keep the risk at Category 3 levels.
CATEGORY 3
WHAT
Two higher tides are forecast: one around 19.7 ft in the early morning (pressure ~1000 hPa) and another near 19.2 ft in the late afternoon (pressure ~998 hPa). These combined factors place conditions close to a flood threshold but do not strongly indicate major flooding.
WHEN
• First high tide around 01:18 on 6/23.
• Second high tide mid-to-late afternoon on 6/23.
IMPACTS
• Minor pooling of water in typically flood-prone coastal spots.
• Little-to-no property damage expected.
Comparisons with past events (e.g., 01/07/2022 Category 4, tidal height ~19.255 ft but with significantly lower pressure near 992.8 hPa) show that Day 3’s tide height is similar, yet its barometric pressure is not as low. Consequently, these conditions remain consistent with Category 3, where some minor flooding concern exists but unlikely to produce widespread damage.
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.
