		आंशिक बदलि (Partly cloudy)	3/8 (26%) to 4/8 (50%) sky covered by cloud
		साधारणतया बदलि (Generally cloudy)	5/8 (51%) to 6/8 (75%) sky covered by cloud

		Intermittent (रोकिदै हुने वर्षा)	Rain occurring and reoccurring at certain intervals
		Widespread (व्यापक बर्षा)	Weather phenomena extensively throughout an area during specified time duration

	बर्षाको संभाव्यता र यसको क्षेत्र (Rainfall probability in percentage and its coverage)	<10%	None used	Isolated	at one or two places (एक-दुई स्थानमा)
		10-30%	Slight Chance	Widely Scattered	at a few places (थोरै स्थानमा)
		30-50%	Chance/possible	Scattered	at a some places (केहि स्थानमा)

		>80%	More likely	Widespread	at most places (अधिकांश स्थानमा)

	संभावित वर्षाको मात्रा (%) ‍= आंकलन X क्षेत्र, जहाँ आंकलन भन्नाले कुनै स्थानमा वर्षा हुन सक्ने संभावना (%) जनाउँदछ भने क्षेत्र भन्नाले तोकिएको स्थानको वर्षा हुन सक्ने संभावित भू-भाग (%) जनाउँदछ। उदाहरणका लागि कुनै स्थानको ८०% क्षेत्रमा ५०% वर्षाको आंकलन गरेको अवस्थामा सो स्थानको संभावित वर्षाको मात्रा (%) ‌‍= ०.५ X०.८ = ४०% हुन आउँछ।
