Marginal and Slight Severe Storm Risks: What to Expect

Severe weather can strike unexpectedly, often leaving communities unprepared and vulnerable. Understanding the nuances of storm risks, especially marginal and slight risks, is essential for your safety. This post will outline what these terms mean, the implications for your daily life, and practical steps to remain informed and safe during severe weather events.

What is Marginal Risk (MRGL)?

Marginal risk, often referred to as MRGL, indicates a low level of severe weather threat. This classification implies that isolated severe storms might occur, but they are likely to be infrequent and limited in intensity. For instance, during a recent marginal risk event in a Midwest state, isolated storms produced wind gusts reaching 50 mph and resulted in minor tree damage across a few neighborhoods.

Although the likelihood of severe weather remains low under this classification, it can still produce some unsettling weather patterns. Storms classified as marginal risk might bring wind gusts between 40-60 mph, small hail, or light, brief heavy rain. According to the National Weather Service, about 10% of days with marginal risk see an actual severe weather event, so vigilance is advised even during these times.

When a marginal risk is issued in your area, it's crucial to stay alert. Regularly tracking local forecasts can help you prepare for any sudden changes in weather.

What is Slight Risk (SLGT)?

Slight risk, or SLGT, represents a moderate level of threat for severe weather events. This classification indicates that scattered severe storms are likely in the affected area. For example, studies show that about 20-30% of days categorized as slight risk will produce storms severe enough to require alerts.

In this category, you could face significant weather conditions, such as hail larger than one inch, damaging winds over 60 mph, and even the potential for tornadoes. This risk level demands that residents stay informed and prepared, as the likelihood of severe weather is considerably higher than in the marginal risk category.

During a slight risk scenario, it is vital to monitor the weather closely. Pay attention to alerts from the National Weather Service; conditions can deteriorate quickly, upgrading from slight risk to more severe alerts.

Steps to Prepare for Marginal and Slight Risks

Preparation is vital as severe weather approaches. Here are essential steps to ensure your safety during marginal and slight risk situations:

• Stay Informed: Monitor weather reports from trusted sources like the National Weather Service or your local meteorologist. Use mobile apps for real-time updates on changing conditions.

  
  

• Create an Emergency Plan: It is important to outline a safety strategy for your household. Identify safe areas in your home (like a basement or interior room) and establish a communication plan for family members.

  
  

• Build an Emergency Kit: Assemble a kit with necessary supplies. Essentials include at least one gallon of water per person per day for three days, non-perishable food, flashlights, batteries, first-aid supplies, and any medications needed.

  
  

• Recognize Warning Signs: Learn to identify different weather alerts like watches (indicating conditions could produce storms) and warnings (where storms are occurring and pose immediate threats).

  
  

By taking these proactive steps, you can significantly safeguard yourself and your loved ones during instances of marginal or slight storm risks.

Stay Prepared, Stay Safe

Understanding storm risk classifications like marginal and slight is essential for staying safe during severe weather. A marginal risk points to isolated storms with a low likelihood of causing severe impact, while a slight risk signals a higher potential for scattered severe weather.

Remain informed, prepare in advance, and recognize signs of severe weather to protect yourself and your loved ones during these unpredictable events. Make checking weather updates a part of your daily routine, especially during seasons prone to storms. Taking these precautions can give you peace of mind and ensure your safety when severe weather approaches.
