Flooding from tropical storm Harvey caused ongoing large-scale U.S. refinery outages on Tuesday, while crude prices rose on the back of supply disruptions in Colombia and Libya.

Refinery shutdowns from the storm helped push U.S. gasoline prices to $1.7799 per gallon on Monday, the most since 2015, although they receded slightly to $1.7342 per gallon by 0648 GMT on Tuesday.

U.S. WTI crude rose 30 cents, or 0.6 percent, to $46.87 a barrel, after falling more than 2 percent in the previous session. International Brent crude futures were up 29 cents, or 0.6 percent, at $52.18 per barrel. Massive floods caused by Harvey forced several U.S. Gulf coast refineries to close, and while some refineries were starting to prepare for re-starts, heavy rains are expected to last through Wednesday after already causing catastrophic flooding in Houston.
