TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
1100 AM PDT SAT JUL 16 2011

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

1. A BROAD LOW PRESSURE SYSTEM LOCATED ALONG THE COAST OF SOUTHEASTERN
MEXICO JUST EAST OF PUERTO ANGEL IS PRODUCING A LARGE AREA OF
CLOUDINESS AND SHOWERS OVER THE GULF OF TEHUANTEPEC AND ADJACENT
LAND AREAS. DEVELOPMENT OF THIS DISTURBANCE...IF ANY...SHOULD BE
SLOW TO OCCUR DUE TO INTERACTION WITH LAND. THIS SYSTEM HAS A LOW
CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES SLOWLY TOWARD THE WEST OR WEST-NORTHWEST.
REGARDLESS OF DEVELOPMENT... LOCALLY HEAVY RAINS COULD OCCUR OVER
PORTIONS OF SOUTHEASTERN MEXICO DURING THE NEXT COUPLE OF DAYS IN
ASSOCIATION WITH THIS SYSTEM.

2. A LOW PRESSURE SYSTEM EMERGING OFF THE COAST OF COSTA RICA IS
PRODUCING SCATTERED THUNDERSTORMS OVER PORTIONS OF CENTRAL
AMERICA AND ADJACENT PACIFIC WATERS. ONLY SLOW DEVELOPMENT IS
EXPECTED FOR THE NEXT DAY OR TWO DUE TO LAND INTERACTION...BUT
ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR MORE SIGNIFICANT
DEVELOPMENT TO OCCUR AFTER THAT TIME. THIS SYSTEM HAS A LOW
CHANCE...20 PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE
NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD AT 5 TO 10 MPH.
LOCALLY HEAVY RAINFALL WILL BE POSSIBLE OVER MUCH OF CENTRAL
AMERICA DURING THE NEXT COUPLE OF DAYS IN ASSOCIATION WITH THIS
LARGE DISTURBANCE.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 48 HOURS.
