Hundreds of thousands were still without power on Monday, including 600,000 in Virginia and Washington, D.C. alone.

One report puts the death toll from the storms at 18.

RMS did not issue an insured-loss estimate, but reports say power outages in some areas are expected to last days, which would affect business-interruption policies.

Columbus, Ohio-based insurer Nationwide says today that, as of late Sunday, it has received 4,804 claims. The company's catastrophe team continue to assess damage to homes, businesses and autos throughout the impacted region.

In Colorado, the weather situation helped firefighters get a handle on the Waldo Canyon Fire that has forced more than 30,000 people from their homes, says RMS.

The U.S. Forest Services Incident Information System says that 347 structures were lost to the fire so far. Reports say that two people were found dead in one home.

As of this morning, 10,000 residencies remained threatened along with 100 commercial structures.

The good news is that the fire is now 55 percent contained and the fire service estimates that it will have full containment by July 12. The combination of higher humidity and cooler temperatures has allowed firefighters to gain the upper hand.

The wildfire, west of Colorado Springs, began on June 23. The cause is still under investigation.

An insurance industry representative has said it's been impossible for adjusters to get into the affected areas because of the ongoing fire, but a few claims have trickled in.

Another Colorado wildfire, the High Park Fire, claimed a total of 259 residencies and is now 100 percent contained.

Between the two fires, Colorado has lost 606 homes and commercial structures.

A spokesman for State Farm says as of today the company has received a total of 369 homeowner claims, 136 of which are a total loss. Of that number, 205 claims are from the Waldo Canyon fire. Of that figure, 59 are a total loss.

He says claims ajusters are continuing to meet with policyholders and set-up appointments to inspect the homes. More claims are expected as more homeowners return to their home, he said.
