St. Louis, often referred to as STL, experiences a variety of severe weather events throughout the year that can cause significant property damage and disruption to daily life. From thunderstorms and tornadoes in spring and summer to ice storms and heavy snowfall in winter, residents of the Greater St. Louis area must be prepared for the potential impacts of these weather events. This article explores the types of storm damage common to the STL region, preventative measures, and steps to take when damage occurs.

 

 

 

Common Types of Storm Damage in STL

 

 

Thunderstorm Damage

 

 

St. Louis sits in a region where warm, moist air from the Gulf of Mexico frequently collides with cooler air masses from the north, creating ideal conditions for severe thunderstorms. These storms typically occur from March through August and can produce multiple hazards:

 

 

 

 

Wind Damage: Straight-line winds exceeding 60 mph can topple trees, damage roofs, and send unsecured objects flying. The "St. Louis Derecho" of July 2006 produced winds over 80 mph that left hundreds of thousands without power.

 

 

 

 

Hail Damage: The STL region regularly experiences hailstorms that can damage roofs, siding, windows, and vehicles. Hailstones in the area have been recorded at sizes exceeding two inches in diameter.

 

 

 

 

Lightning Strikes: St. Louis averages 40-50 thunderstorm days annually, with each storm producing numerous lightning strikes that can damage electrical systems, start fires, and destroy trees.

 

 

 

Tornado Damage

 

 

Located on the eastern edge of "Tornado Alley," St. Louis has experienced several devastating tornadoes throughout its history. The most notable include the 1896 St. Louis-East St. Louis Tornado (one of the deadliest in U.S. history), the 1927 tornado that damaged 5,000 buildings, and the 2011 Good Friday tornado that damaged Lambert International Airport.

 

 

 

 

Tornado damage is categorized by the Enhanced Fujita (EF) Scale, ranging from EF0 (minor damage) to EF5 (catastrophic damage). Even EF1 tornadoes with winds of 86-110 mph can cause significant roof damage and overturn mobile homes.

 

 

 

Flooding

 

 

The confluence of the Mississippi and Missouri Rivers makes the STL region particularly susceptible to flooding. The Great Flood of 1993 caused billions in damage across the region. More recently, flash flooding has become increasingly problematic in urban areas where concrete and asphalt prevent water absorption, leading to rapid runoff.

 

 

 

Winter Storm Damage

 

 

Winter brings its own set of challenges to St. If you liked this post and you would such as to receive more info pertaining to Local Pro Tips kindly check out the webpage. Louis:

 

 

 

 

Ice Storms: When freezing rain accumulates on trees and power lines, the weight can cause branches to break and power lines to fall. The 2006 ice storm left over 500,000 residents without power, some for more than a week.

 

 

 

 

Snow Load: While less common than ice damage, heavy snow can accumulate on roofs, potentially causing structural damage, especially to older buildings or those with flat roofs.

 

 

 

 

Freeze-Thaw Cycles: St. Louis's fluctuating winter temperatures can cause repeated freezing and thawing, leading to foundation cracks, roof damage, and broken water pipes.

 

 

 

Preventative Measures

 

 

Property Maintenance

 

 

Regular maintenance is the first line of defense against storm damage:

 

 

 

Trim trees regularly, removing dead or weak branches that could fall during storms

 

Clean gutters and downspouts to prevent water backup and ice dams

 

Inspect and repair roof shingles or tiles before storm season

 

Secure or store outdoor furniture, toys, and decorations that could become projectiles in high winds

 

 

Structural Improvements

 

 

For long-term storm resilience, consider these improvements:

 

 

 

Install impact-resistant roofing materials rated for high winds and hail

 

Use hurricane straps or clips to strengthen roof-to-wall connections

 

Consider installing storm shutters or impact-resistant windows

 

Elevate utilities in flood-prone areas

 

Ensure proper grading around your foundation to direct water away from your home

 

 

Emergency Preparedness

 

 

Being prepared for storms includes:

 

 

 

Creating an emergency plan for your household

 

Assembling an emergency kit with water, non-perishable food, medications, flashlights, batteries, and a weather radio

 

Knowing how to shut off utilities

 

Having a designated shelter area within your home for tornadoes

 

Maintaining adequate insurance coverage for all potential storm hazards

 

 

When Damage Occurs

 

 

Immediate Safety Steps

 

 

If your property sustains storm damage:

 

 

 

Ensure everyone's safety first

 

If there are downed power lines, stay away and call the utility company

 

Check for gas leaks, water damage, and structural damage

 

If the structure appears unsafe, evacuate immediately

 

 

Documentation and Insurance

 

 

Before beginning cleanup:

 

 

 

Document all damage with photographs and videos

 

Make a detailed inventory of damaged items

 

Contact your insurance company promptly to file a claim

 

Keep receipts for all emergency repairs and temporary lodging

 

 

Selecting Contractors

 

 

Unfortunately, storm damage often brings "storm chasers" – contractors who follow severe weather events looking for quick work, sometimes performing substandard repairs. To protect yourself:

 

 

 

Work with local, established contractors with proper licensing and insurance

 

Get multiple written estimates

 

Check references and online reviews

 

Never pay the full amount upfront

 

Be wary of contractors who pressure you to sign contracts immediately

 

 

Community Resources in STL

 

 

 

The St. Louis region has several resources available to residents affected by storm damage:

 

 

 

The American Red Cross of Eastern Missouri provides emergency shelter and assistance

 

The United Way's 211 helpline connects residents with various support services

 

Missouri and Illinois state emergency management agencies offer disaster assistance programs

 

Local municipalities often provide special debris pickup after major storms

 

The Metropolitan St. Louis Sewer District (MSD) offers programs to address flooding issues

 

 

Climate Change Implications

 

 

 

Climate scientists suggest that the St. Louis region may experience more frequent and intense storms as climate change progresses. This includes:

 

 

 

More days with extreme heat, potentially fueling stronger thunderstorms

 

Increased precipitation intensity, leading to more flash flooding

 

Potentially longer tornado seasons

 

More variability in winter weather patterns

 

 

These changes underscore the importance of strengthening infrastructure and individual preparedness in the region.

 

 

Conclusion

 

 

 

Storm damage is an unfortunate reality for residents of the St. Louis region. However, understanding the risks, taking preventative measures, and knowing how to respond when damage occurs can significantly reduce the impact of these weather events. By maintaining properties, implementing structural improvements, and staying prepared, STL residents can build resilience against the region's diverse and sometimes severe weather patterns. Additionally, community resources and proper insurance coverage provide vital support when prevention isn't enough. As weather patterns continue to evolve, adaptation and preparation will become increasingly important for protecting homes and lives in the Gateway City.
