Tropical Depression Arlene Discussion Number   9
NWS National Hurricane Center Miami FL       AL022023
1000 AM CDT Sat Jun 03 2023

Arlene has weakened to a tropical depression.  The Air Force
Hurricane Hunters have been investigating Arlene this morning and
found that the minimum pressure has risen to 1000 mb and maximum
winds have decreased to 30 kt or less.  This weakening trend is due
to strong vertical wind shear and dry air that has wrapped into the
circulation, and continued weakening is forecast.  Deep convection
associated with Arlene has been separating from the low-level
center, and there are only a few patches of convection left more
than 90 n mi northeast of the center.  If these trends continue,
Arlene will be designated a remnant low later today.

The tropical depression is moving south-southeastward at about 6
kt.  The system will turn to the east today as it moves within a
deep-layer trough, which will likely increase rainfall across
portions of southern Florida through tonight.
