...TROPICAL WAVES...

A tropical wave in the eastern Atlantic extends along 24W/25W
from 01W to 16W near the Cabo Verde Islands, moving W at around
15 kt. Scattered moderate convection is observed west of the wave

Weather Outlook assigns a low (20%) probability of generating a
tropical cyclone in the next 48 hours, and a low (30%)
probability over the next seven days.

Waves at 00:05 URC on 6/21/23.

Invest Area (AL93): Shower and thunderstorm activity has diminished
during the past several hours in association with a tropical wave
located several hundred miles southwest of the Cabo Verde Islands.
Its axis is along 34W S of 15N moving W at 10 to 15 kt. A 1011
mb low pressure is analyzed along the wave axis near 09.5N34W.
Currently, convection is limited. However, environmental conditions
appear conducive for further development of this system, and a
tropical depression will likely form during the next couple of
days while the system moves westward at 10 to 15 kt across the
eastern and central tropical Atlantic. The latest Tropical
Weather Outlook gives this system a high chance of tropical
cyclone formation in the next 48 hours, as well as over the next
seven days. Refer to the latest NHC Tropical Weather Outlook at
www.hurricanes.gov for more details.

...TROPICAL WAVES...

development of this system, and a tropical depression will likely
form during the next couple of days while the system moves
westward across the central tropical Atlantic. The latest
Tropical Weather Outlook assigns a high (70%) chance of tropical
cyclone formation in the next 48 hours, and a high (80%) chance
over the next seven days. Refer to the latest NHC Tropical Weather
Outlook at www.hurricanes.gov for more details.
