A few convective cells continue to pulse over 100 n mi northeast of
Polo’s center, but overall the cyclone has not produced persistent,
organized deep convection since yesterday evening.  Therefore, Polo
is being designated as a remnant low.  A recent ASCAT pass sampled
the eastern part of Polo’s circulation and showed winds around 25
kt, so it is assumed that 30-kt winds are still occurring closer to
the center.  Moderate westerly shear, marginally warm waters, and a
dry environment should cause Polo’s winds to gradually decrease,
and the circulation is expected to open up into a trough by 36
hours, per the latest global model guidance.
 
Polo is moving just south of due west (265/10 kt), steered by a
low- to mid-level ridge to its north.  This general motion is
expected to continue until the low dissipates, and the NHC track
forecast is down the middle of the tightly packed guidance envelope.

Forecasts issued by the National Weather Service, under AWIPS
header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at
