The following surface synoptic and sub-synoptic/mesoscale features are depicted: highs, lows, fronts, troughs, outflow boundaries, squall lines, drylines. The domain includes much of North America, the Western Atlantic and Eastern Pacific oceans, and the Gulf of Mexico. In addition, a coded surface bulletin is created that describes in text format the locations of highs and lows, fronts, and troughs.

NOTE:  The Pacific Ocean analyses north of 30oN and Atlantic Ocean analyses north of 31oN are provided by NCEP's Ocean Prediction Center.
The Tropical Prediction Center analyzes features south of 31oN in the Atlantic (including Florida, Mexico and the Gulf of Mexico) and south of 30oN in the Pacific Ocean.
