Waves at 12:05 UTC on 7/8/23.

A tropical wave extends along 26W/27W south of 19N, moving west
at around 15 kt. No significant convection is observed at this
time.

association with this wave. Seas of 8 to 9 ft follow the wave
based on altimeter data. Looking ahead, this wave is forecast to
bring an increase in winds and seas across the waters just E of
the Leeward Islands on Tue, and over the NE Caribbean on Wed.

coastal waters. Moderate to fresh SE winds are noted on the E side
of the wave axis. Moisture associated with this feature will spread
over Hispaniola today increasing the chance of showers and thunderstorms.

tropical wave, mainly N of 13N while an altimeter pass shows seas
of 7 to 9 ft on the E side of the wave axis.

Looks like something that would have been spinning once conditions (shear, SAL) improve.

[cycloneye]

Waves at 12:05 UTC on 7/11/23.

A eastern Atlantic tropical wave has its axis along 24W from 05N
to 15N. It is moving westward at 10-15 kt. A small cluster of
moderate convection is noted where the wave meets the ITCZ near
10N24W.

An active and well defined tropical wave is approaching the Lesser
Antilles. Its axis extends from 19N54W to near the Suriname/Guyana
border. This wave is moving westward at about 20 kt. Scattered
moderate to isolated strong convection is seen mainly ahead of the
wave axis from 14N to 18N between 51W and 61W. Resent scatterometer
data indicate fresh to strong easterly winds on either side of
the wave, mainly N of 15N. Seas of 6 to 9 ft are within these
winds. The wave is located SE of an upper-level trough that extends
across the Leeward Islands into the eastern Caribbean to near
15N70W. This is likely enhancing the convective activity
associated to the wave that is already affecting the Lesser
Antilles, mainly S of Guadeloupe.

A western Caribbean Sea tropical wave has its axis along 81W,
south of 21N. It is moving westward at 10 to 15 kt. This wave

convection is present near the northern portion of the wave axis
affecting parts of central Cuba and the Cayman Islands. A cluster
of moderate to strong convection is over eastern Panama.
