Why Your Lights Flicker During Storms in Ithaca — And When to Call an Electrician

If your lights flicker every time a storm rolls through Ithaca, you are not alone. Between aging electrical infrastructure, heavy rain, wind, and seasonal power demand, flickering lights are one of the most common electrical issues homeowners experience in Tompkins County.

Sometimes it is harmless. Other times, it is an early warning sign of a larger electrical problem that should be addressed before it becomes a safety hazard.

Here is what causes flickering lights, what you can safely check yourself, and when it is time to call a licensed electrician like Pleasant Valley Electric.

Common Causes of Flickering Lights During Storms

1. Power Grid Fluctuations

Strong winds and lightning can affect utility lines, transformers, and neighborhood electrical systems. Brief flickers during severe weather are often caused by momentary utility interruptions.

If the flickering only happens during storms and resolves quickly, the issue may be outside your home.

2. Loose Electrical Connections

Loose wiring connections inside outlets, switches, or your electrical panel can cause lights to flicker intermittently. Storm vibrations and moisture can sometimes make these issues more noticeable.

Loose connections should never be ignored. They can lead to overheating, damaged wiring, or electrical fires.

3. Overloaded Circuits

Modern homes use far more electricity than older homes were originally designed for. If your panel is overloaded, large appliances turning on during storms — such as sump pumps, HVAC systems, or refrigerators — can cause lights to dim or flicker.

This is especially common in homes with outdated electrical panels.

4. Water Intrusion

Moisture entering outdoor fixtures, exterior wiring, meter bases, or service connections can create electrical instability during rainstorms.

Signs of moisture-related electrical problems include:

• Flickering only during rain
• Buzzing sounds
• Burning smells
• Tripped breakers
• Outdoor outlets stopping working

5. Failing Electrical Panels

Older breaker panels can struggle to handle modern electrical loads. If flickering happens frequently — even outside storms — your home may need a panel upgrade.

Warning signs include:

• Breakers tripping often
• Warm outlets or switches
• Burning odors
• Dimming lights when appliances start
• Rust or corrosion around the panel

What You Can Check Safely

Before calling an electrician, you can safely:

• Check whether neighbors also lost power
• Reset a tripped breaker once
• Test whether flickering happens in one room or throughout the house
• Unplug large appliances temporarily to reduce electrical load

Do not:

• Open your electrical panel
• Touch wet outlets
• Attempt DIY wiring repairs
• Ignore burning smells or sparking

Electrical troubleshooting should always be handled by licensed professionals.

When to Call an Electrician Immediately

Contact an electrician right away if you notice:

• Burning smells
• Buzzing outlets
• Sparks
• Frequent breaker trips
• Partial power loss
• Water near electrical equipment
• Flickering throughout the entire house
• Warm switches or outlets

These symptoms can indicate dangerous wiring or panel issues.

Preventing Electrical Problems During Storm Season

A few preventative upgrades can dramatically improve electrical safety and reliability:

• Whole-home surge protection
