/SOUTH PACIFIC OCEANS/070600Z-080600ZAUG2020//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR 
16.2N 125.0E, APPROXIMATELY 237 NM NORTHEAST OF MANILA, PHILIPPINES. 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 070108Z METOP-B 89 
GHZ IMAGE DEPICT A WEAK BROAD LOW LEVEL CIRCULATION (LLC) WITH 
FLARING CONVECTION IN THE EASTERN AND SOUTHERN QUADRANTS BUT NO 
DEFINED SHALLOW BANDING. RECENT ASCAT IMAGERY REVEALS A DEFINED 
BROAD CIRCULATION WITH 5-10KT WINDS OVER THE WESTERN SEMICIRCLE AND 
10-15KT WINDS OVER THE EASTERN SEMICIRCLE. INVEST 94W IS CURRENTLY 
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD EQUATORWARD 
UPPER LEVEL FLOW, LOW (<15KTS) VERTICAL WIND SHEAR, AND WARM (29-
31C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GENERAL 
AGREEMENT THAT INVEST 94W WILL TRACK NORTHWARD INTO THE EAST CHINA 
SEA WHILE CONTINUING TO DEVELOP AND INTENSIFY IN THE NEXT 24-36 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//

Tropical Weather Outlook

For the eastern North Pacific...east of 140 degrees west longitude:

Showers and thunderstorms have increased since yesterday in 
association with a tropical wave located south of the Gulf of 
Tehuantepec.  Environmental conditions are forecast to 
become increasingly conducive for development, and a tropical 
depression is expected to form early next week while the system 
moves generally west-northwestward, offshore of southwestern Mexico.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...high...80 percent.

800 AM EDT Fri Aug 7 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A tropical wave is located several hundred miles west-southwest of 
the Cabo Verde Islands.  Slow development of this system is 
possible during the next couple of days as it moves slowly westward. 
After that time, environmental conditions are expected to become 
less conducive for development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
