(Updates prices; adds comment, contract details, NEW YORK dateline) NEW YORK/LONDON, Feb 20 (Reuters) - White sugar futures fell on Tuesday, pressured by a stronger U.S. dollar and a looming global supply glut, while arabica coffee extended last week's losses to reach its lowest in more than two months.
* May white sugar settled down $3.60, or 1 percent, at $357.90 per tonne, remaining within the range held the past month.
* The market was under pressure from a stronger U.S. dollar and ample supplies due to strong production in India, Thailand and the European Union this season, traders said.
* However, participants said they were closely monitoring weather in the EU amid signs of an approaching cold snap that could hurt crops.
* "Notably, an increased number of frost days are expected over the European continent as temperatures are forecast to plummet," Marex Spectron said in a note.
* May raw sugar settled up 0.01 cent, or 0.1 percent, at 13.29 cents per lb.
* The March premium over May <SBH8-K8> fell to 0.07 cent, from 0.1 cent on Friday, but maintained a premium on the possibility of fewer available supplies for delivery ahead of expiry at the end of the month.
* May arabica coffee settled down 0.75 cent, or 0.6 percent, at $1.197 per lb, after falling to $1.195, the second-position contract's lowest since Dec. 13.
* The market's 3 percent drop on Friday, when selling ahead

pressured prices, triggered chart-based sell signals as prices extended losses below long-term moving averages and recent session lows, traders said.
* "The chart looks pretty ugly and the speculators covered a fair bit more than the market had thought," one dealer said. "So they have scope to sell."
* The spot arabica premium over robusta fell to 36 cents per lb, the lowest in nearly four months.
* May robusta coffee settled up $29, or 1.7 percent, at $1,770 per tonne, after touching $1,733, its lowest since Jan. 31.
* The March robusta premium over May <LRCH8-K8> rose to $43, the highest for the contract.

* May New York cocoa settled up $14, or 0.7 percent, at $2,148 per tonne.
* The market shrugged off expectations for a global surplus, as bean arrivals at top grower Ivory Coast ports neared year-ago levels, as focus shifted to quality concerns following hot weather in most Ivorian regions, traders said.
