LONDON, Nov 30 (Reuters) - Arabica coffee futures on ICE were lower on Monday, slipping from the prior session's 2-1/2 month high, with forecast rains expected to bring some relief to crops in southern Brazil.

COFFEE

* March arabica coffee fell 1.15 cents, or 0.9% to $1.2305 per lb by 1135 GMT. The benchmark second position rose to a peak of $1.2480 on Friday, its highest since mid-September.

* Dealers said rains over the next few days could aid the outlook for crops in southern Brazil although some of the damage from the recent dry spell is likely to be irreversible.

* March robusta coffee fell $12, or 0.85%, to $1,401 a tonne.

* Vietnam exported 70,000 tonnes of coffee in November, down 37.5% from a year earlier, government data released on Sunday showed.

SUGAR

* March raw sugar fell 0.04 cents, or 0.3%, to 14.78 cents per lb.

* The market continued to await an announcement from India on its export policy for the current season with the lack of any export subsidies so far effectively keeping much of the country's surplus out of the international market.

* Marex Spectron said in a weekly update that it believed there would be a subsidy but it would probably not be announced until the end of December or early January.

* "We hear a tonnage of 5 million tonnes mentioned more frequently... time is running out for India to export much more than 5 million tonnes," Marex Spectron analyst Robin Shaw said.

* March white sugar fell $3.10, or 0.8%, to $401.60 a tonne.

COCOA

* March New York cocoa was down $28, or 1.0%, at $2,738 a tonne.

* Dealers said a strong start to the main crop in top grower Ivory Coast remained a bearish influence although the low level of exchange stocks continued to provide support.

* March London cocoa fell 12 pounds, or 0.6%, to 1,857 pounds a tonne.

* The expiry of December London cocoa options on Monday should provide a short-term focus. (Reporting by Nigel Hunt; Editing by Ken Ferris)
