Redondo Beach, WA
CATEGORY 2
WHAT
No significant flooding is expected. Tide levels around 20.1 ft combined with high barometric pressure (around 1025 hPa) and low NOAA flood likelihood (2.2%) suggest no coastal flooding of concern.
WHEN
Minor tide peaks near 05:00 AM PST.
IMPACTS
No notable flooding impacts anticipated at this level. Low-lying shore areas may see slight water encroachment, but damage is not expected.
High barometric pressure greatly reduces flooding risk. This day’s measured tide height is similar to some Category 3 historical events, but the much lower NOAA flooding likelihood—in combination with stable weather conditions—supports a Category 2 determination.
CATEGORY 2
WHAT
Again, minimal to no coastal flooding is expected. The highest tide, near 20.4 ft at around 05:30 AM PST, aligns with continued high barometric pressure (exceeding 1025 hPa) and a very low (1.8%) NOAA flood likelihood.
WHEN
Main tide peaks early morning near 05:30 AM PST and a secondary peak in the mid-afternoon (15:30 PST), both under favorable conditions.
IMPACTS
No significant impacts are anticipated. Low-lying spots along the shoreline should remain unaffected by notable inundation.
Although these tide heights can warrant closer monitoring in some circumstances, the extremely high barometric pressure and a lower NOAA likelihood reduce concerns for this date.
CATEGORY 3
WHAT
Close to a flood event and worth active monitoring. Tide levels around 20.5 ft at approximately 06:00 AM PST combine with moderately lower air pressure (about 1019–1020 hPa) and a higher NOAA flood likelihood (5.3%) compared to the previous two days.
WHEN
Greatest risk around the morning high tide near 06:00 AM PST. An afternoon high tide near 16:30 PST is also elevated but slightly lower in height.
IMPACTS
Minor flooding of shoreline paths or very low-lying areas is possible. Damage to property is unlikely under current conditions.
Historically, Barometric pressure around 1020 hPa paired with a tide near 20+ ft has produced moderate flooding risk. However, the NOAA likelihood is still below levels seen in prior Category 4 events. Therefore, flooding concerns remain modest, but it is prudent to stay alert.
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.
