Struck by Hail

Hailstones pose a genuine threat to human safety when they reach sufficient size and velocity. These frozen projectiles can cause injuries ranging from minor bruises to life-threatening trauma, depending on their size and the circumstances of impact. Most hail injuries occur during severe thunderstorms when people are caught outdoors without adequate shelter.

Symptoms

Common signs and symptoms of Struck by Hail include:

Bruising or welts where hail struck the body
Cuts or lacerations from sharp ice edges
Headache after being struck on the head
Swelling at impact sites
Pain that worsens with movement
Bleeding from scalp wounds
Dizziness following head impact
Nausea after head injury
Confusion or disorientation
Visible lumps or bumps on struck areas
Difficulty moving affected limbs
Sharp pain when touching injured areas

When to see a doctor

If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.

Causes & Risk Factors

Several factors can contribute to Struck by Hail.

Hail forms when raindrops are carried upward by powerful thunderstorm updrafts into extremely cold areas of the atmosphere.

Hail forms when raindrops are carried upward by powerful thunderstorm updrafts into extremely cold areas of the atmosphere. These droplets freeze and begin falling, but strong updrafts can lift them back up repeatedly, adding layers of ice with each cycle. The longer this process continues, the larger the hailstone grows before finally becoming too heavy for the updraft to support.

The damage potential of hailstones depends on several key factors.

The damage potential of hailstones depends on several key factors. Size matters most - while pea-sized hail rarely causes injury, golf ball-sized stones can inflict serious harm, and baseball-sized hail can be lethal. Wind speed affects the angle and force of impact, with strong horizontal winds driving hail sideways rather than straight down. The terminal velocity of hailstones increases dramatically with size, creating kinetic energy capable of causing blunt force trauma.

Most hail injuries occur when people are caught in the open during storms.

Most hail injuries occur when people are caught in the open during storms. Common scenarios include being outdoors during recreational activities, working in exposed areas like construction sites or farms, or attempting to protect property like vehicles during a hailstorm. The sudden onset of severe weather can leave people with little time to find adequate shelter, particularly in open areas like parking lots, beaches, or hiking trails.

Risk Factors

  • Living in or visiting hail-prone regions like Tornado Alley
  • Working outdoors during storm season
  • Participating in outdoor recreational activities
  • Failing to monitor weather forecasts and warnings
  • Being in open areas with limited shelter options
  • Attempting to protect vehicles or property during storms
  • Having mobility limitations that slow shelter-seeking
  • Being caught in sudden severe weather changes
  • Working in agriculture or construction
  • Playing outdoor sports during unstable weather

Diagnosis

How healthcare professionals diagnose Struck by Hail:

  • 1

    Medical professionals diagnose hail injuries through physical examination and patient history about the weather event.

    Medical professionals diagnose hail injuries through physical examination and patient history about the weather event. Doctors look for patterns of injury consistent with multiple impacts from above, often seeing a combination of bruises, cuts, and swelling on the head, shoulders, and other exposed areas. The timing correlation with reported severe weather helps confirm the cause.

  • 2

    Imaging studies may be necessary depending on the severity and location of injuries.

    Imaging studies may be necessary depending on the severity and location of injuries. X-rays can reveal fractures if hailstones struck bones like the skull, ribs, or limbs with sufficient force. CT scans become essential when head injuries are suspected, particularly if the patient shows signs of confusion, persistent headache, or other neurological symptoms that could indicate traumatic brain injury.

    The diagnostic process also involves assessing for complications that might not be immediately apparent.

    The diagnostic process also involves assessing for complications that might not be immediately apparent. Large hailstones can cause internal injuries, and doctors may order additional tests if they suspect damage to organs beneath impact sites. A thorough neurological examination helps rule out concussion or more serious brain injury, especially important given that the head is often the primary target for falling hail.

Complications

  • Most hail injuries heal completely without lasting problems, but complications can occur depending on the severity of impact and location of injuries.
  • Head injuries pose the greatest concern, with potential for concussion, skull fractures, or in extreme cases, traumatic brain injury.
  • Even seemingly minor head impacts can cause post-concussion symptoms like persistent headaches, dizziness, or cognitive difficulties that may last weeks or months.
  • Infection represents another potential complication, particularly with deeper cuts or puncture wounds caused by sharp ice.
  • Contamination from debris mixed with hailstones can introduce bacteria into wounds.
  • Proper wound cleaning and monitoring help prevent this complication, but some injuries may require antibiotic treatment.
  • Large bruises or hematomas can occasionally lead to complications if they compress nerves or blood vessels, though this is uncommon with typical hail injuries.

Prevention

  • The most effective prevention strategy involves staying informed about weather conditions and taking immediate shelter when severe thunderstorms threaten.
  • Weather apps, emergency alerts, and local forecasts provide advance warning of hail-prone storms.
  • When thunderstorms approach, the safest locations are sturdy buildings, preferably away from windows that could be broken by large hailstones.
  • For those caught outdoors when hail begins, finding any overhead protection becomes critical.
  • Cars provide excellent shelter, though parking under overpasses or bridges offers even better protection.
  • If no substantial shelter exists, look for anything that can shield your head and upper body - picnic tables, playground equipment, or even large trees, though these carry lightning risk.
  • Never try to run to distant shelter through heavy hail; instead, protect your head with your hands, backpack, or any available covering and seek the nearest protection.
  • Long-term prevention involves understanding your local hail risk and planning accordingly.
  • People in high-risk areas should identify multiple shelter options along regular routes and activities.
  • Outdoor event planners need contingency plans for severe weather.
  • Workers in exposed industries should receive training on weather awareness and have access to sturdy shelter.
  • Simple preparations like keeping a jacket or blanket in your car can provide head protection if you're caught in the open during a sudden hailstorm.

Initial treatment for hail injuries follows standard trauma care protocols, with immediate attention to any head injuries or signs of serious trauma.

Initial treatment for hail injuries follows standard trauma care protocols, with immediate attention to any head injuries or signs of serious trauma. For minor injuries like bruises and small cuts, basic first aid suffices - cleaning wounds, applying ice to reduce swelling, and monitoring for signs of infection. Pain management with over-the-counter medications helps address discomfort from multiple impact sites.
