FOR THE EASTERN NORTH PACIFIC...EAST OF 140 DEGREES WEST LONGITUDE..

TWO TROPICAL CYCLONES...TROPICAL STORMS BEATRIZ AND CALVIN...FORMED
DURING THE MONTH OF JUNE.

BEATRIZ DEVELOPED FROM A TROPICAL WAVE...BECOMING A DEPRESSION ON
THE 21ST ABOUT 275 MILES SOUTH OF ZIHUATANEJO MEXICO.  THE CYCLONE
STRENGTHENED SLOWLY AS IT MOVED WEST-NORTHWESTWARD WELL OFFSHORE THE
MEXICAN COAST...BECOMING A TROPICAL STORM ON THE 22ND AND REACHING
ITS PEAK INTENSITY OF 45 KT EARLY ON THE 23RD.  EASTERLY WIND SHEAR
HALTED DEVELOPMENT AND BEATRIZ WEAKENED TO A DEPRESSION OVER COOL
WATERS EARLY ON THE 24TH.  THE CYCLONE DEGENERATED TO A NON-
CONVECTIVE REMANT LOW LATER THAT DAY ABOUT 290 MILES SOUTH-SOUTHWEST
OF CABO SAN LUCAS MEXICO...AND DISSIPATED TWO DAYS LATER.

CALVIN DEVELOPED FROM A TROPICAL WAVE THAT CROSSED CENTRAL AMERICA
AROUND 21 JUNE.  THE AREA OF DISTURBED WEATHER ASSOCIATED WITH THE
WAVE MOVED SLOWLY WESTWARD TO THE SOUTH OF EASTERN MEXICO FOR A FEW
DAYS...WITH UNSTEADY DEVELOPMENT.  FINALLY ON 26 JUNE A TROPICAL
DEPRESSION FORMED ABOUT 250 MILES SOUTHEAST OF ACAPULCO.  IT BECAME
A TROPICAL STORM EARLY ON THE 27TH AND REACHED ITS PEAK INTENSITY
OF 45 KT LATER THAT DAY.  SIMILAR TO BEATRIZ...THE DEVELOPMENT
TREND WAS REVERSED BY EASTERLY WIND SHEAR.  CALVIN WEAKENED TO A
DEPRESSION ON THE 28TH AND DEGENERATED INTO A LOW CLOUD SWIRL THAT
NIGHT.  THE REMNANT CIRCULATION...EMBEDDED WITHIN A BROADER AREA OF
LOW PRESSURE...CONTINUED TOWARD THE WEST-NORTHWEST WHILE PRODUCING
INTERMITTENT DEEP BUT DISORGANIZED CONVECTION.  CURRENTLY...THE
LOW-LEVEL CIRCULATION IS LOCATED ABOUT 350 MILES SOUTH OF CABO SAN
LUCAS MEXICO...MOVING OVER COOLER WATERS.
