Update, 1:50 a.m. - Fire departments have cleared the site and US 41-A is reopening.

Material is continuing to burn off in one of the tanks at this time. Webster County Emergency Management Director Jeremy Moore says a representative of the company that operates the tanks is going to monitor the site through the night.

Kenergy has a crew on site to repair the damaged power line, but as of now, there's no estimate when power might be restored.

Moore says heavy rain that accompanied the lightning helped reduce the fire hazard following the explosion. A tanker truck had just recently picked up oil at the tank battery as well.

WEBSTER COUNTY (KY) -- An "oil well related explosion and fire," shut down traffic on a local road, and caused a power outage for many in the area on Monday night.

Just after 10 p.m., Webster County 911 Dispatch received a call about the fire off of US-41 Alternate, between Providence and Dixon.

According to Webster County Emergency Management Director Jeremy Moore, lightning struck an oil storage battery causing the tanks to explode.  The top of one of the tanks landed in the roadway.  Two other tanks were on fire when firefighters arrived.

As a result, US 41-A is closed to all through traffic between KY 670/The Providence Bypass at mile point 0.5 and KY 270 at mile point 3.0 to allow emergency responders unrestricted access to the site.

KYTC personnel are setting up a detour via KY 270 and KY 109 through Clay around the explosion site.

The explosion also damaged some 3-phase power lines at the site, causing a power outage in the area.
