Aug 4 (Reuters) - U.S. natural gas futures on Tuesday edged up to their highest since January as liquefied natural gas exports surge higher and on forecasts the weather will remain hot through late August after Hurricane Isaias blows through, keeping air conditioners humming. Front-month gas futures rose 3.9 cents, or 1.9%, to $2.140 per million British thermal units at 8:37 a.m. EDT (1237 GMT), putting the contract on track for its highest close since Jan. 14. That puts the contract into overbought territory with a Relative Strength Index (RSI) over 70 for a second day in a row for the first time since November 2019. On Monday, volume in the front-month, which soared almost 17%, topped 381,000 contracts, its highest since hitting a record 495,196 in November 2018 during the market's most volatile period, when it rose 18% one day and fell 17% the next. Hurricane Isaias, which hit North Carolina overnight, broke the heat wave that has blanketed much of the country since late June. The storm left more than 600,000 homes and businesses in North Carolina and Virginia without power early Tuesday and was expected to cause more damage as it scrapes north up the East Coast. But with hot weather expected to return after Isaias blows away, data provider Refinitiv projected U.S. demand, including exports, will rise from an average of 88.6 bcfd this week to 91.8 bcfd next week. That, however, is a little lower than Refinitiv's outlook on Monday as higher prices cause power generators to burn more coal instead of gas. U.S. LNG exports are on track to rise for the first time in six months as the amount of pipeline gas flowing to the plants rose to 4.0 bcfd in August from a 21-month low of 3.3 bcfd in July when buyers canceled dozens of cargoes.
