Post-Tropical Cyclone Arlene Discussion Number 10
NWS National Hurricane Center Miami FL AL022023
500 PM EDT Sat Jun 03 2023
Arlene has lacked organized deep convection for quite some time now,
since about 07Z. There have been a few short-lived small bursts of
convection in the northeast quadrant, but they have been getting
quickly sheared off and lack organization. Therefore, Arlene no
longer meets the definition of a tropical cyclone and the system is
now a remnant low. The initial intensity is estimated to be 25 kt
based on a partial ASCAT pass, surface observations, and the earlier
reconnaissance data. Strong vertical wind shear and dry air should
continue to cause weakening, and this system is expected to open
into a trough on Sunday.
The low pressure area is moving south-southeastward at 6 kt. A turn
to the east is expected tonight and that motion should continue
until the system dissipates. The remnant low will likely enhance
rainfall over portions of southern Florida through tonight.
This is the last NHC advisory on Arlene. For more information,
