Tropical Storm Paul Discussion Number 7
NWS National Hurricane Center Miami FL EP182018
800 PM PDT Sun Sep 09 2018
Paul is looking very ragged this evening. The low-level center has
become completely exposed, with the nearest deep convection
displaced about 70 n mi to its southwest. The intensity has been
held at 40 kt, deferring to earlier ASCAT data which showed a wide
swath of 35-40 kt winds. Given the structure of Paul, any
intensification seems very unlikely, so gradual weakening is now
forecast through the end of the period. By day 4, a combination of
cold SSTs and dry, stable air should cause the cyclone to become a
remnant low. The new NHC forecast shows faster weakening than
before, and is now closer to the intensity consensus through 120 h.
The low-level swirl that makes up most of Paul has wobbled a bit
this evening, but a longer-term motion estimate is still
northwestward, or 320/9 kt. The global models are in good agreement
that Paul will continue northwestward for another day or so, before
gradually turning westward as it weakens and eventually becomes a
remnant low. No significant changes were made to the track
forecast, which remains very near the multi-model consensus
throughout the forecast period.
