1007 ET - Natural gas futures are higher after retreating Thursday on a slightly bigger-than-expected weekly storage build, while effects from Hurricane Isaias are seen mixed with small offshore production losses offset by impacts on demand. LNG exports will likely decrease due to shipping delays, and demand is expected to be lost to power outages and flooding, NatGasWeather.com says in a note. "The storm won't contribute much to lost cooling demand due to temperatures already being relatively comfortable," the forecaster adds. Nymex natural gas is up 1% at $3.201/mmBtu.
