development of this system is possible during the next day or two
before environmental conditions become unfavorable.

WITHIN 100 NM EITHER SIDE OF A LINE FROM 12.8N 20.7W TO 14.6N 21.3W
WITHIN THE NEXT 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT

KNOTS.

THE DAY. ENVIRONMENTAL CONDITIONS APPEAR CONDUCIVE FOR FURTHER
DEVELOPMENT, AND THIS SYSTEM COULD BECOME A TROPICAL DEPRESSION
DURING THE NEXT 24 HOURS WHILE IT DRIFTS NORTH-NORTHWESTWARD.

NHC展望亦同時一舉提升至50%/50%
1. Showers and thunderstorms associated with a small area of low
pressure, located a few hundred miles south-southeast of the Cabo
Verde Islands have increased and become better organized during the
day.  Environmental conditions appear conducive for further
development, and this system could become a tropical depression  
during the next day or so while it drifts generally
north-northwestward.  After that time, environmental conditions are
forecast to become less favorable for development.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

200 AM CVT Sun Aug 02 2020

Scatterometer data around 2130 UTC confirmed that the system north
of the Cabo Verde islands no longer has a well-defined center. The
scatterometer data showed that the southwest semicircle of the
system consists of only light and variable winds, and the strongest
winds associated with the system have decreased to around 20 kt. The
system lacks deep convection and a combination of cool underlying
water and a dry surrounding environment will prevent regeneration.
This is the last NHC advisory on this system.

UTC 2130附近的散射儀數據確認系統向北
佛得角群島中的一部分不再具有明確定義的中心。的
散射儀數據顯示,
系統僅由微風和可變風組成,並且最強
與該系統相關的風已經減少到約20 kt。的
系統缺乏深度對流以及很酷的底層
水和乾燥的周圍環境會阻止再生。
這是該系統上最新的NHC諮詢。
