Physical natural gas for Tuesday delivery was driven higher by forecasts of heat and humidity in large eastern markets, and other market points were quick to follow.

Traders are bullish on natural gas. “I am a scale-down buyer of natural gas,” Alan Harry, trader and principal with Harry’s RE Trust in New York told NGI. “One of the reasons I am so bullish is we are ending the summer with natural gas below $3, which means a lot of gas that could have been kept in storage or in the market is gone.

“I also see a lot of gas going out through LNG, and that will have an impact on natural gas this winter. We’ve been fortunate to have bearish weather, and if we had had bullish weather prices would have been much, much higher. The rig count is not increasing, and all that is going to make for a very tight situation when we need the natural gas.

“Right now I am a scale in buyer at $2.90 down to $2.78, and if it breaks $2.77, I would get out of all longs. I think we will hit $3.57 to $3.65 in the next two months.

Short term traders are a little more skeptical. “This market needs to trade above $3 and hold before we can see any real advance,” a New York floor trader said. “Although there may be stops above $3, we have been above $3 on numerous occasions only to give up 15 cents.”

The National Hurricane Center (NHC) in its 2 p.m. EDT report was following two Atlantic tropical systems. It said that activity has increased Monday in association with the remnants of Harvey, but the system still lacks a well-defined center of circulation. Some development of this disturbance is still possible before it reaches the coast of Belize or the Yucatan Peninsula early Tuesday. The system is forecast to move into the Bay of Campeche early Wednesday, where environmental conditions are expected to be conducive for redevelopment into a tropical cyclone. NHC puts the likelihood of tropical storm formation at 90%.

NHC said that a trough of low pressure over the central Bahamas could show slow development the next several days while it moves west-northwestward across the Bahamas and then turns northwestward or northward near Florida and the adjacent waters. It estimated the chance of becoming a tropical storm in the next five days at 40%.
