PLEASE SEE THE SPECIAL FEATURES SECTION ABOVE FOR INFORMATION ON
HURRICANE RACHEL LOCATED WEST-SOUTHWEST OF BAJA CALIFORNIA,
MEXICO, AND INVEST 92E OFFSHORE OF SOUTHERN MEXICO.
HURRICANE RACHEL CONTINUES TO MOVE AWAY FROM THE OFFSHORE WATERS
OF BAJA CALIFORNIA, HOWEVER, MODERATE TO FRESH SOUTHERLY WINDS
AND ROUGH SEAS PERSIST WEST OF 115W AND SOUTH OF 27N. MEANWHILE,
A DEVELOPING LOW PRESSURE, MONITORED AS INVEST 92E, IS PRODUCING
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ACROSS THE OFFSHORE
WATERS OF SOUTHERN AND SW MEXICO. THIS SYSTEM IS ALSO GENERATING
FRESH TO STRONG WINDS AND MODERATE SEAS, MAINLY BETWEEN 96W AND
103W. ELSEWHERE, MODERATE OR WEAKER WINDS AND SLIGHT TO MODERATE
SEAS ARE PREVALENT.
FOR THE FORECAST, HURRICANE RACHEL WILL CONTINUE TO MOVE AWAY
FROM THE OFFSHORE WATERS OF BAJA CALIFORNIA OVER THE NEXT FEW
DAYS AND WEAKEN. LATER, A WEAKENING RACHEL MAY REACH THE OFFSHORE
ZONES OF BAJA CALIFORNIA SAT EVENING INTO SUN AS IT TURNS BACK
TOWARD THE NORTHEAST. THIS WILL BRING AN INCREASE IN WINDS AND
BUILDING SEAS TO THE AREA. A BROAD AREA OF LOW PRESSURE LOCATED
OFFSHORE OF SOUTHERN MEXICO IS PRODUCING DISORGANIZED SHOWERS AND
THUNDERSTORMS. ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR
GRADUAL DEVELOPMENT, AND A TROPICAL DEPRESSION IS EXPECTED TO
FORM WITHIN THE NEXT DAY OR SO WHILE THE SYSTEM MOVES SLOWLY
WEST-NORTHWESTWARD TO NORTHWESTWARD. A STORM WARNING HAS BEEN
ISSUED FOR THE INCREASING WINDS AND BUILDING SEAS ASSOCIATED WITH
THIS LOW PRESSURE. REGARDLESS OF DEVELOPMENT, HEAVY RAINFALL IS
FORECAST ACROSS PORTIONS OF SOUTHERN AND SOUTHWESTERN MEXICO OVER
THE NEXT FEW DAYS. INTERESTS ALONG THE COAST OF SOUTHWESTERN
MEXICO SHOULD MONITOR THE PROGRESS OF THIS SYSTEM. THE
DISTURBANCE HAS A HIGH CHANCE OF FORMATION IN THE NEXT 48 HOURS.

FOR THE FORECAST, RACHEL WILL MOVE TO 21.1N 122.1W THIS
AFTERNOON, WEAKEN TO A TROPICAL STORM NEAR 21.7N 123.3W THU
MORNING, 22.2N 124.6W THU AFTERNOON, 22.5N 125.2W FRI MORNING,
22.9N 124.8W FRI AFTERNOON, AND 24.1N 123.0W SAT MORNING. RACHEL
WILL BECOME POST-TROPICAL AS IT MOVES TO THE 29.2N 117.5W EARLY
SUN. A WEAKENING RACHEL SHOULD REACH THE OFFSHORE ZONES WEST OF
BAJA CALIFORNIA NORTE SAT EVENING AS IT TURNS BACK TOWARD THE
NORTHEAST. A BROAD AREA OF LOW PRESSURE LOCATED OFFSHORE
OF SOUTHERN MEXICO IS PRODUCING DISORGANIZED SHOWERS AND
THUNDERSTORMS. ENVIRONMENTAL CONDITIONS APPEAR FAVORABLE FOR
GRADUAL DEVELOPMENT, AND A TROPICAL DEPRESSION IS EXPECTED TO
FORM WITHIN THE NEXT DAY OR SO WHILE THE SYSTEM MOVES SLOWLY
WEST-NORTHWESTWARD TO NORTHWESTWARD. A STORM WARNING HAS BEEN
ISSUED FOR THE INCREASING WINDS AND BUILDING SEAS ASSOCIATED WITH
THIS LOW PRESSURE LIKELY AFFECTING THE EASTERN WATERS LATE THIS
WEEK INTO THE WEEKEND. THE DISTURBANCE HAS A HIGH CHANCE OF
FORMATION IN THE NEXT 48 HOURS.
