Flood Watch

Redondo Beach, WA

Day 1: 2025-06-22

CATEGORY 3

WHAT
Tides are projected to reach around 19.7 feet near midnight (with slightly lower midday high tides), coupled with a moderately low barometric pressure near 999.7 hPa. These conditions bring water levels close to minor flooding thresholds, though significant property damage is not expected.

WHEN
From late night (around midnight) on June 22 through the early morning hours when tides are forecast highest.

IMPACTS
Minor inundation could occur in especially low-lying areas and nearshore locations. Isolated, brief impacts to shoreline roads or parking lots are possible, though broader-scale flooding or damage is unlikely at this time.

ADDITIONAL DETAILS...

• The highest tide for Day 1 occurs just before 01:00 AM and should peak around 19.7 feet.
• Although the barometric pressure is slightly lower (999.72 hPa) compared to average, it remains considerably higher than critical historical low-pressure flood events (typically near or below 992.8 hPa).
• Light winds (generally under 5 mph) further limit the potential for larger storm surge.
• Historically, tides under 20 feet combined with moderately low barometric pressure have most often resulted in Category 3 conditions: worth monitoring but unlikely to cause major impacts.


Day 2: 2025-06-23

CATEGORY 3

WHAT
Two moderate high tides (around 19.65 feet just after midnight, and roughly 19.17 feet late afternoon) are again paired with barometric pressures in the range of 1000.9 to 1003.9 hPa. These levels remain close to minor flood thresholds but with no strong indication of significant flooding or property damage.

WHEN
• First peak around 01:18 AM.
• Second peak in the mid-afternoon hours around 16:36 PM.

IMPACTS
Similar to Day 1, only minor inundations possible in low-lying beach areas. No substantial or extended flooding anticipated.

ADDITIONAL DETAILS...

• The preceding day’s relatively calm weather pattern and the lack of notably low pressure (generally above 1000 hPa) reduce the severity of any coastal flooding.
• Wind speeds remain moderate to low, further decreasing the risk of wave-driven flooding.
• Past events of Category 4-level flooding typically involved slightly higher tides (exceeding 20 ft) or drastically lower barometric pressure—both of which are not expected on Day 2.


Day 3: 2025-06-24

CATEGORY 3

WHAT
Highest tides approach roughly 19.80 feet late afternoon (around 17:30), and barometric pressures hold near 1002.8 hPa. Conditions still hover below thresholds typically associated with damaging floods.

WHEN
• Minor high tide overnight around 02:06 AM (up to about 19.48 ft).
• Peak high tide later in the day around 17:30.

IMPACTS
Localized ponding in especially vulnerable coastal spots is possible. Widespread flooding or significant structural impacts are not expected.

ADDITIONAL DETAILS...

• Although Day 3 shows slightly higher tide heights (around 19.8 ft) than earlier in the period, the barometric pressure remains relatively stable and well above critical storm-pressure levels.
• Historical comparisons show that tides must typically exceed 20–21 ft in conjunction with significantly low pressure to create Category 4 or higher flood risks.
• With no NOAA flood risk data available for these dates, the assessment relies on historical tide-pressure benchmarks indicating close monitoring rather than major flooding.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.

CATEGORY KEY

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.
