W OF 105W...
A MIDDLE/UPPER LEVEL TROUGH HAS ITS AXIS EXTENDING THROUGH 
32N122W TO NEAR 23N132W. CYCLONIC FLOW IS LOCATED E OF THE 
TROUGH INTO MEXICO AND WITHIN FIVE TO SIX DEGREES W OF THE 
TROUGH. A JET STREAM IS CLEARLY EVIDENT ON WATER VAPOR IMAGERY 
AND ORIGINATES NEAR THE DATE LINE AND CONTINUES EASTWARD THROUGH 
18N140W TO 18N127W. THE JET THEN TURNS NE THROUGH 25N121W AND

128W. SEAS WILL INCREASE TO 10 FEET IN 48 HOURS. NORTHEAST TRADE 
WINDS TO 20 KNOTS ARE LOCATED FROM 09N TO 20N W OF 125W.
