Tropical Storm Lidia Discussion Number 14
NWS National Hurricane Center Miami FL EP142017
900 PM MDT Fri Sep 01 2017
The terrain of the Baja California peninsula has taken a toll on
Lidia. The cloud pattern has become disorganized, and deep
convection has decreased with only a few strong patches remaining
near the center. Based on tonight's satellite intensity estimates
and continuity, the initial intensity is generously set at 45 kt.
It appears that the strongest winds are occurring in the eastern
half of the circulation and mainly over the Sea of Cortes. The
interaction with land and cold waters will result in additional
weakening, and Lidia is forecast to be a remnant low in about 24 to
36 hours or even sooner.
Lidia has continued on a steady motion toward northwest or 320
degrees at 10 kt. The flow pattern resulting from a high over
Mexico and a large low to the west will continue to steer
Lidia northwestward for a day or two. Thereafter, Lidia is expected
to be a shallow cyclone steered by the low-level easterly flow. The
NHC forecast is very similar to the previous one and is close to the
multi-model consensus.
Despite weakening, the heavy rainfall threat will continue over
northwestern Mexico and the Baja California peninsula during
the next couple of days. Moisture from the cyclone could
reach the southwestern United States over the weekend.
