Insured losses from recent wildfires in Texas will easily top the $US100 million ($94 million) mark, according to the Insurance Council of Texas.

The council says the fire losses are the “worst on record in Texas”, in a year that has seen drought conditions across the southern US.

This comes on top of the recent damage from Hurricane Irene, with US insured losses now estimated as high as $US6.6 billion ($6.3 billion).

But the US has avoided damage from Hurricane Katia, a hurricane which has been as strong as category three but which is now curving back out to sea after passing between Bermuda and the US east coast.

The latest named storms, Tropical Storms Lee, Maria and Nate, have brought rain across the southern US, Caribbean and Mexico.

Catastrophe modeller Eqecat says Tropical Storm Maria could present a risk to the US mainland next week, and is expected to strengthen but may not reach hurricane strength.

Tropical Storm Nate, which is “nearly stationary” in the southern Gulf of Mexico, will probably affect southern Texas, but the current forecast includes only a slight probability of it achieving hurricane strength.
