SYNOPSIS
THE ATLANTIC RIDGE WILL STRENGTHEN MODESTLY ACROSS
THE REGION THROUGH SAT, BEHIND A TROPICAL WAVE MOVING EXITING
THE AREA THIS MORNING. THIS WILL LEAD TO FRESHENING WINDS AND
INCREASING SEAS THROUGH EARLY SAT. AN AREA OF SHOWERS AND
THUNDERSTORMS ASSOCIATED WITH A STRONG TROPICAL WAVE LOCATED OVER
THE CENTRAL ATLANTIC NEAR 42W IS SHOWING SOME SIGNS OF
ORGANIZATION. ENVIRONMENTAL CONDITIONS ARE FORECAST TO BE
CONDUCIVE FOR DEVELOPMENT DURING THE NEXT DAY OR SO, AND A
TROPICAL DEPRESSION WILL LIKELY FORM WHILE THE SYSTEM MOVES
WESTWARD TO WEST- NORTHWESTWARD ACROSS THE CENTRAL TROPICAL
ATLANTIC. HOWEVER, BY FRIDAY, UPPER-LEVEL WINDS ARE LIKELY TO
BECOME TOO STRONG FOR DEVELOPMENT AS THE SYSTEM APPROACHES THE
LESSER ANTILLES. THIS SYSTEM IS FORECAST TO REACH THE LESSER
ANTILLES SAT MORNING, AND REACH 70W SUN MORNING.
