Photo Gallery: Herndon Area Storm Damage

Northern Virginia woke up to power outages and scattered tree limbs and debris in roads after a powerful storm hit the area Friday night. 

Verizon and AT&T customers have reported being without cell and home phoen service Saturday. Many are also without power in the area, which could be dangerous with today's high temps in the high 90s and heat index of 105. 

At about 7:30 a.m. Dominion Power spokeswoman Le-Ha Anderson said about 450,000 in Northern Virginia are without power. That includes about 242,750 in Fairfax. In the Herndon area most of the outages are in the area on the north side of the town limits, between Dranesville Road and Fairfax County Parkway.

"It's way too soon to say when power will be restored," said Anderson, adding she expects it to be "multiple days" before power is fully restored to all homes. "Today we're focusing on assessing the damage."

If your power is out, report it to Dominion Virginia Power by calling 866-DOM-HELP (866-366-4357), or by visiting the Dominion Storm Center, even if you think your neighbor has already reported it.

There is a chance for more thunderstorms this afternoon, but they are not expected to be nearly as severe as they were last night. Temperatures will cool into the upper 70s tonight.
