THESE CLOUDS ORIGINATE FROM THUNDERSTORMS IN THE WAKE ISLAND...MARSHALL ISLANDS AREA LOCATED AROUND 2000 MILES WEST SOUTHWEST OF KAUAI. THE RIBBON OF CIRRUS IS ABOUT 450 MILES WIDE WITH THE THICKEST PART COVERING MOST OF KAUAI COUNTY. THIS RIBBON OF CIRRUS ALSO MARK THE POSITION OF THE SUB TROPICAL JET STREAM WHICH CONTAIN WINDS OF 55 TO 75 MPH. THE CIRRUS EXTENDS TO 800 MILES TO THE NORTHEAST OF KAUAI...TO 30N 147W BEFORE TURNING EAST AND DISSIPATING. THE CIRRUS IS THIN ENOUGH TO VIEW THE LOW LEVEL CLOUDS SITUATION EAST OF KAUAI.

A TROUGH EXTENDS NORTHEASTWARD FROM THE LOW THROUGH 34N155W TO ANOTHER UPPER LOW AT 37N141W. ANOTHER TROUGH EXTENDS SOUTHWESTWARD FROM THE FIRST LOW THROUGH 25N173W TO 24N178E.
