Severe Thunderstorm Warning: What Montgomery County Residents Should Do Now as Storms Bring Hail and Flooding to the Philadelphia Region

Is a tornado coming to Montgomery County after the thunderstorm warning?

The National Weather Service has issued a severe thunderstorm warning for Montgomery County, with potential for damaging winds and hail. While thunderstorms can occasionally spawn tornadoes, no tornado watch has been announced as of now. Residents should remain alert for any changes in weather conditions.

Historical data shows that tornadoes in this region are rare but not impossible. The most recent tornado warning was issued on July 1st, though no touchdowns were reported. During severe thunderstorms, it’s crucial to monitor weather alerts and have a plan to seek shelter in an interior room on the lowest floor if a tornado warning is issued.

Tornadoes can develop rapidly from severe thunderstorms, especially when certain atmospheric conditions align. While we’re not currently under a tornado watch, residents should be aware of the signs like a dark, greenish sky or loud roar similar to a freight train.

How bad will the flooding get in my neighborhood?

The current storm system is expected to produce heavy rainfall of 1-3 inches within a short period, which could lead to flash flooding, especially in low-lying areas and near small streams. Areas that typically experience flooding during heavy rains are particularly vulnerable.

Previous storm events have shown that Chester County tends to be hit hardest by flooding, with Downingtown area seeing over 7 inches of rain in past events. Montgomery County residents should be prepared for possible road closures and basement flooding in areas with poor drainage.

Most flood-prone areas in Montgomery County

• Schuylkill River watershed areas
• Perkiomen Creek lowlands
• Smaller streams with inadequate drainage
• Urban areas with outdated stormwater systems

Where can I get real-time severe weather alerts for Montgomery County?

Montgomery County operates the ReadyMontco alert system, which provides real-time notifications about severe weather and other emergencies. Residents can sign up for free at the county’s emergency management website.

Additionally, the National Weather Service offers text alerts for severe weather warnings. Many residents also use weather radio or trusted weather apps for instant notifications. During previous severe weather events, emergency alerts have proven crucial for timely warnings about approaching storms.

Will my power go out during this severe thunderstorm?

With predicted wind gusts up to 60 mph and the possibility of hail, power outages are likely in some areas. Trees and power lines may be damaged by the strong winds, particularly where the ground is already saturated from recent rains.

Utility companies have crews on standby, but restoration times could vary depending on the extent of damage. Residents should charge essential devices and consider backup power options for medical equipment.

Preparing for potential power outages

1. Charge phones and portable chargers
2. Have flashlights with fresh batteries ready
3. Keep refrigerator and freezer doors closed during outage
4. Know how to manually open garage doors

How long will this severe weather last in Philadelphia area?

The current severe weather threat is expected to persist for about 6-8 hours as the storm system moves through the region. The most intense period of thunderstorms is likely to last 2-3 hours in any given location, with the peak occurring during the late afternoon and early evening.

However, flooding concerns may continue even after the rain stops as water makes its way through streams and rivers. The weather service warns that some areas may experience multiple rounds of thunderstorms as the system moves through.

This storm system is showing characteristics similar to the one that drenched the region on June 8th, 2021, when some areas received over 7 inches of rain. The duration of intense rainfall today could be shorter, but the ground is already saturated from recent rains, increasing flood potential.

What’s the difference between a storm watch and warning?

Many residents confuse these two important terms. A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms to develop, while a Severe Thunderstorm Warning means a severe storm has been detected and is imminent or occurring.

The current warning means immediate action is needed. Strong wind gusts, large hail, and dangerous lightning are occurring in Montgomery County. Residents should move indoors immediately and stay away from windows.

My basement flooded last time – how can I prevent damage this storm?

With heavy rain expected, basement flooding is a serious concern for many homeowners. Some preventive measures include clearing gutters and downspouts, ensuring sump pumps are working, and moving valuables to higher levels.

For chronic flooding issues, more permanent solutions like French drains or backwater valves may be necessary. During the June 2021 storms, many homeowners reported extensive basement flooding that could have been mitigated with proper preparation.

Last-minute flood prevention tips

• Extend downspouts at least 5 feet from foundation
• Clear storm drains near your property
• Sandbag doorways if prone to flooding
• Test sump pump operation

The most important thing right now is safety. Property can be replaced, but lives can’t. If emergency officials say to evacuate, don’t hesitate – just go immediately to higher ground.
