TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

1100 AM PDT THU JUN 16 2011

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

A BROAD AREA OF LOW PRESSURE HAS FORMED SEVERAL HUNDRED MILES TO THE

SOUTHEAST OF THE GULF OF TEHUANTEPEC. ALTHOUGH THE ASSOCIATED

SHOWER AND THUNDERSTORM ACTIVITY REMAINS DISORGANIZED...

ENVIRONMENTAL CONDITIONS ARE FORECAST TO BE FAVORABLE FOR FURTHER

DEVELOPMENT OF THIS LOW DURING THE NEXT COUPLE OF DAYS. THERE IS A

MEDIUM CHANCE...40 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL

CYCLONE DURING THE NEXT 48 HOURS AS IT BEGINS TO MOVE SLOWLY WEST-

NORTHWESTWARD.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.

Despite what ever the models drank last night, Lixion seems to think conditions are conducive for slow development...

500 AM PDT FRI JUN 17 2011

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

EARLY MORNING SATELLITE IMAGES INDICATE THAT CLOUDINESS AND

THUNDERSTORMS ASSOCIATED WITH A BROAD AREA OF LOW PRESSURE CENTERED

SEVERAL HUNDRED MILES SOUTH OF THE GULF OF TEHUANTEPEC HAS NOT

BECOME ANY BETTER ORGANIZED. HOWEVER...ENVIRONMENTAL CONDITIONS

STILL APPEAR TO BE FAVORABLE FOR SOME DEVELOPMENT AND THERE IS A

MEDIUM CHANCE...40 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL

CYCLONE OVER THE NEXT 48 HOURS AS IT MOVES SLOWLY TOWARD THE

WEST-NORTHWEST.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.

I think it actually looks a tad better this morning-- there's some consolidation and a bit of turning. Motion is WNW, I see.

I agree with you Josh as the low levels are slowly coming together, but convection needs to become better organized. Give it another 24-30 hours of this slow organization, then we could see a depression or tropical storm.

Good ole Lixion raises development chances to 50%...

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

1100 AM PDT FRI JUN 17 2011

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

CLOUDINESS AND THUNDERSTORMS ASSOCIATED WITH A BROAD AREA OF LOW

PRESSURE ARE CENTERED SEVERAL HUNDRED MILES SOUTH OF THE GULF OF

TEHUANTEPEC. THIS ACTIVITY HAS BECOME A LITTLE MORE CONCENTRATED

DURING THE PAST SEVERAL HOURS AND ENVIRONMENTAL CONDITIONS APPEAR

TO BE FAVORABLE FOR FURTHER DEVELOPMENT. THERE IS A MEDIUM CHANCE

...50 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE OVER THE

NEXT 48 HOURS AS IT MOVES SLOWLY TOWARD THE WEST-NORTHWEST.

REGARDLESS OF ADDITIONAL DEVELOPMENT...SHOWERS WILL CONTINUE TO

AFFECT PORTIONS OF THE COAST OF SOUTHEASTERN MEXICO TODAY AND

TOMORROW.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.

Oh, and we have a cherry...

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

500 PM PDT FRI JUN 17 2011

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

SHOWER AND THUNDERSTORM ACTIVITY ASSOCIATED WITH A BROAD LOW

PRESSURE SYSTEM CENTERED SEVERAL HUNDRED MILES SOUTH OF THE GULF OF

TEHUANTEPEC HAS CONTINUED TO BECOME A LITTLE BETTER ORGANIZED

DURING THE PAST SEVERAL HOURS. ENVIRONMENTAL CONDITIONS APPEAR

CONDUCIVE FOR ADDITIONAL DEVELOPMENT...AND A TROPICAL DEPRESSION

COULD FORM OVER THE NEXT DAY OR TWO. THERE IS A HIGH CHANCE...60

PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE DURING THE

NEXT 48 HOURS AS IT MOVES WEST TO WEST-NORTHWESTWARD NEAR 10 MPH.

REGARDLESS OF FURTHER DEVELOPMENT...SHOWERS AND THUNDERSTORMS COULD

AFFECT PORTIONS OF THE COAST OF SOUTHEASTERN MEXICO THROUGH SUNDAY.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.

Microwave imagery suggests things are slowly coming together for 92E. The southern semi circle still lacks deep convection, but the NHC states a depression may form in the next 24 hours or so. It still appears to be a sloppy system, but that may enhance rain chances across the Western Gulf region as we move ahead...

TD 2E tomorrow...?

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

500 PM PDT SAT JUN 18 2011

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

SATELLITE DATA FROM EARLIER TODAY INDICATE THAT THE CENTER OF

CIRCULATION OF A LOW PRESSURE AREA CENTERED ABOUT 325 MILES

SOUTH-SOUTHEAST OF ACAPULCO MEXICO IS BECOMING BETTER DEFINED.

SHOWER AND THUNDERSTORM ACTIVITY IS A LITTLE BIT MORE CONCENTRATED

NEAR THE CENTER...AND ADDITIONAL ORGANIZATION COULD RESULT IN THE

FORMATION OF A TROPICAL DEPRESSION TONIGHT OR ON SUNDAY. THERE IS

A HIGH CHANCE...70 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL

CYCLONE DURING THE NEXT 48 HOURS AS IT MOVES WEST-NORTHWESTWARD

NEAR 10 MPH. INTERESTS ALONG THE SOUTHWESTERN COAST OF MEXICO

SHOULD MONITOR THE PROGRESS OF THIS LOW OVER THE NEXT FEW DAYS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.

The central plains trough is gonna weaken the Nern MX ridge. This translates into weaker steering currents and a more poleward motion. But as the trough swings east the ridge will rebuild again, probably just in time to avert a head on collision with land.

Special NHC statement-- looks like it's going to pop real soon.

Quote worthy.

SPECIAL TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

230 AM PDT SUN JUN 19 2011

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

DURING THE PAST FEW HOURS...THUNDERSTORM ACTIVITY HAS INCREASED AND

BECOME BETTER ORGANIZED NEAR THE CENTER OF A LARGE LOW PRESSURE

SYSTEM THAT IS LOCATED ABOUT 280 MILES SOUTH-SOUTHEAST OF

ACAPULCO... AND A TROPICAL DEPRESSION MAY BE FORMING. IF THIS

RECENT DEVELOPMENT TREND CONTINUES...THEN ADVISORIES COULD BE

INITIATED ON THIS SYSTEM LATER THIS MORNING. THERE IS A HIGH

CHANCE...90 PERCENT...OF THIS LOW PRESSURE AREA BECOMING A TROPICAL

CYCLONE DURING THE NEXT 24 HOURS AS IT MOVES WEST-NORTHWESTWARD AT

ABOUT 10 MPH. INTERESTS ALONG THE SOUTHWESTERN COAST OF MEXICO

SHOULD MONITOR THE PROGRESS OF THIS LARGE DISTURBANCE SINCE IT

COULD BRING STRONG GUSTY WINDS AND HEAVY RAINS TO THE REGION DURING

THE NEXT COUPLE OF DAYS.

ELSEWHERE...TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE

NEXT 48 HOURS.
