TROPICAL STORM CRISTINA DISCUSSION NUMBER 23
NWS NATIONAL HURRICANE CENTER MIAMI FL EP032014
800 PM PDT SAT JUN 14 2014
Deep convection associated with Cristina has dissipated during
the last several hours, with the circulation now just a swirl of low
clouds. Dvorak intensity estimates have decreased considerably,
and, as a result, the initial intensity is lowered to 35 kt based
on a blend of CI- and Final-T numbers. A continued rapid spin down
of the vortex is forecast by all of the intensity guidance, and
Cristina should weaken to a remnant low within 24 hours. Global
models then show the remnant low degenerating into an open trough in
a few days. The NHC intensity forecast now calls for Cristina to
become post-tropical in 24 hours, though this could occur sooner.
Now that Cristina is a shallow cyclone, its movement has become more
westerly as it is steered by a low- to mid-level ridge to the north.
A longer-term average of center fixes, however, gives an initial
motion estimate of 295/05. As the ridge to the north weakens during
the next day or so, Cristina is expected to resume a west-
northwestward or northwestward motion at a slow forward speed until
dissipation. The NHC track forecast is similar to the previous one
but adjusted slightly to the left during the first 24 hours as a
result of the more westward initial motion.
