Tropical Storm Ana Discussion Number   5
NWS National Hurricane Center Miami FL       AL012021
500 AM AST Sun May 23 2021

Satellite images indicate that Ana has contracted significantly
since yesterday and now has a compact area of moderate convection
around the center.  Given the tight low-level circulation, small
radius of maximum wind, and compact central convection, Ana is
now estimated to have transitioned from a subtropical storm to a
tropical storm. The initial intensity remains 40 kt for this
advisory based on the earlier ASCAT data, which indicated that the
tropical-storm-force winds were confined to the south side of the
circulation.

Ana is not expected to be around much longer.  The storm is headed
for an environment of lower SSTs, drier air, and increasing wind
shear.  All of these factors should cause the compact cyclone to
lose strength and ultimately open into a trough in 24 to 36 hours.
In fact, some of the models suggest that the storm could dissipate
even sooner than that.  The remnants of Ana will likely be absorbed
by a cold front on Monday.

The storm continues to increase its forward speed, and the initial
motion is now estimated to be 045/10 kt. A faster motion to the
northeast is expected until the cyclone dissipates.
