Crude futures briefly jumped more than $2 a barrel Tuesday after the Energy Department raised its oil-price forecast by $6 a barrel and as traders remain worried that summer storms in the Gulf of Mexico could curtail petroleum output.
The Energy Department, which oversees U.S. supply and demand statistics, said Tuesday that it expects oil prices to average $59 a barrel through September, up from its estimate of $53 a barrel a month ago.
While the impact of Hurricane Dennis was not as bad as originally feared - even with BP reporting that one of its offshore platforms was listing - traders are keeping an eye on freshly brewing Tropical Storm Emily.
Adding to bullish sentiment were expectations that Wednesday's inventory snapshot from the U.S. government would show a decline in crude oil inventories.
