TROPICAL STORM ODILE DISCUSSION NUMBER 24
NWS NATIONAL HURRICANE CENTER MIAMI FL EP152014
800 PM PDT MON SEP 15 2014
The tropical cyclone continues to have a fairly well-organized
appearance on satellite imagery, but deep convection has been
thinning out. Applying a typical inland decay rate, the current
intensity is set at a rather uncertain 55 kt. Continued weakening
is forecast, and the system is likely to fall below tropical storm
strength in a day or so. The official wind speed forecast is
similar to the latest decay-SHIPS guidance and to the intensity
model consensus, and now shows Odile becoming a remnant low by 72
hours.
Odile's heading has shifted a little to the right, and the
initial motion estimate is 340/11 kt. A mid-level ridge to the
east of the cyclone should cause a turn toward the north in a day or
so, and a low- to mid-level trough near southern California is
likely to turn Odile or its remnant low north-northeastward in 2-3
days. The official track forecast is a little faster than the
previous one and is close to the latest dynamical model consensus
forecast, TVCE.
Moisture is forecast to be advected northward by Odile's
circulation over the next few days. This, along with the slow
motion of Odile or its remnant low, will likely result in locally
heavy rains and possible flooding over portions of the southwestern
United States. Please see information from your local weather
office for more details.
