Southeast Pennsylvania is under a Coastal Flood Advisory today, Wednesday, October 25th, 2023. High tides combined with strong northeast winds are creating a heightened risk of coastal flooding across the region. This article provides an update on the current situation, outlining areas most affected and offering crucial safety advice to help residents prepare for and mitigate the potential impacts of this weather event. This advisory is particularly important for those living in low-lying areas and coastal communities.

Affected Areas in Southeast PA

This Coastal Flood Advisory Southeast PA primarily impacts coastal regions of several counties. The highest risk areas include specific towns and vulnerable locations within:

• Delaware County: Communities along the Delaware River, including low-lying areas near Marcus Hook and Chester. Areas with poor drainage systems are especially susceptible. The Chester Creek area is also of particular concern.

• Chester County: Low-lying areas near the Delaware River in Chester County, particularly around Downingtown and Avondale, are at increased risk of flooding. Areas with a history of flooding should be especially vigilant.

• Philadelphia County: While not directly coastal, parts of Philadelphia along the Delaware River could experience minor flooding, especially areas with poor drainage or below-average elevation.

Specific vulnerable areas within these counties include:

• Low-lying areas near the Delaware River in Chester County.
• Coastal communities in Delaware County experiencing high tide surges.
• Areas with poor drainage systems throughout the affected counties.
• Riverfront properties and those adjacent to creeks and streams.

Current Conditions and Predictions

Current conditions show sustained northeast winds of 20-25 mph with gusts up to 35 mph. These strong winds are driving higher than normal tides and increasing the risk of coastal flooding. The National Weather Service (NWS) Philadelphia/Mount Holly office is providing regular updates.

Key predictions from the NWS include:

• High tide expected at 2:15 PM EDT with a predicted height of 7.2 feet. This is significantly above the normal high tide for this time of year.
• Sustained winds of 20-25 mph with gusts up to 35 mph are expected to persist through the afternoon. This will continue to exacerbate the flooding risk.
• Flood warnings may be upgraded to a more serious alert depending on the observed conditions and continued wind speeds. Residents should closely monitor updated forecasts.
• Minor coastal flooding is possible even outside of official flood zones. Exercise caution even if your area is not specifically mentioned in official warnings.

Safety Precautions and Recommendations

The safety of residents is paramount. Following these precautions is vital during this Coastal Flood Advisory Southeast PA:

• Avoid driving through flooded areas – "Turn Around, Don't Drown." Flooded roads can be deceptively dangerous; the depth of the water may be difficult to judge, and the roadbed beneath could be damaged.
• Secure outdoor furniture and any loose objects that could be swept away. Strong winds can easily move lightweight items.
• Monitor weather reports and follow instructions from local emergency services. Stay updated on changing conditions and any official advisories.
• Be aware of rip currents if venturing near the coast. Strong winds can create hazardous conditions in coastal waters.
• Have an emergency kit prepared. This should include flashlights, batteries, bottled water, non-perishable food, and a first-aid kit.
• Charge your electronic devices. This will ensure you can communicate and receive critical updates if power is interrupted.
• Have a communication plan in place. Determine how you will contact family and friends if cell service is disrupted.
