* Within-day gas was up 0.65 pence at 59.65 pence per therm at 0920 GMT.

* Average daily temperatures in Britain are expected to be 4.3 degrees Celsius on Wednesday and dip to 4.1C on Thursday, before going up over the weekend.

* Demand is forecast to be above the season's norm at 332 million cubic metres (mcm), but ample supply from pipeline flows, liquified natural gas (LNG) deliveries and storage withdrawals are expected to keep the UK gas system over-supplied by 26 mcm, National Grid data showed.

* Gas flows from Norway grew by around 19 mcm to 109 mcm/day, compared to Tuesday, according to Refinitiv Eikon data.

* Flows through the BBL pipeline from Belgium rose by 10 mcm to 28 mcm/day. LNG send-out was up by 7 mcm to 66 mcm/day.

* Britain expects four liquefied natural gas tankers by Saturday.

* Peak wind generation is forecast at nearly 6 gigawatts (GW) and fall to almost 5 GW on Thursday, which could mean more gas is needed from gas-to-power plants for electricity generation.
