* Market charts sharpest daily decline in nearly six weeks

(Updates latest prices)

28/09/2016 (Reuters) - Malaysian palm oil futures slid on Tuesday evening from the previous session's five-month high to a one-week low, tracking weaker-performing rival oils and with low exports weighing on sentiment.

Benchmark palm oil futures for December fell 1.9 percent on the Bursa Malaysia Derivatives Exchange to close at 2,663 ringgit ($646) a tonne. They had earlier touched a low of 2,657 ringgit, the weakest level since Sept. 19, and registered the sharpest daily decline in nearly six weeks.

Traded volumes stood at 33,942 lots of 25 tonnes each in the evening, below the 2015 daily average of 44,600.

"Production is gradually improving but demand is still lacking," one Kuala Lumpur-based trader said, adding that the market was also correcting from its highs.

Palm has been trading above 2,650 ringgit in the past five sessions, reaching a five-month high of 2,737 ringgit on Monday.

It rose 3.1 percent last week for its strongest weekly gain since Aug. 12.

While there will be a seasonal increase in output this month and in October, the gains are expected to be below average because of last year's crop-damaging El Nino weather pattern. August output in Malaysia gained 7.3 percent to 1.7 million tonnes. (MYPOMP-CPOTT)

Other traders said prices were pressured by weakness in soyoil, with which palm oil competes in the global vegetable oils market.

Export of palm oil products are expected to slip this month on weaker demand from top consumers China and India. Traders expect demand to be slow until the end of the year as cold temperatures in the northern hemisphere solidify the tropical oil, making it less appealing to buyers.

Shipments for the Sept. 1-25 period declined nearly 16 percent compared with the same period in August, cargo surveyor data showed on Monday.

In competing vegetable oils, the Chicago Board of Trade's soybean oil December contract slid 0.7 percent while the January soybean oil contract on the Dalian Commodity Exchange dropped 0.4 percent.
