HURRICANE CRISTINA DISCUSSION NUMBER 15
NWS NATIONAL HURRICANE CENTER MIAMI FL EP032014
800 PM PDT THU JUN 12 2014
Cristina has weakened during the last several hours. The eye has
lost definition and is now barely apparent in satellite images. In
addition, the cloud pattern has become asymmetric with the
convection being eroded to the west of the center, likely due to
mid-level dry air and some westerly shear. Dvorak intensity numbers
from all agencies are decreasing, and the initial wind speed is
lowered to 105 kt based on those estimates. Cristina is expected to
continue weakening as it moves toward a more hostile environment,
including progressively colder waters during the next several days.
The NHC intensity forecast is lower than the previous one to account
for the observed weakening, and is in good agreement with the
intensity model consensus IVCN.
The hurricane is moving west-northwestward at about 7 kt. A
west-northwestward to northwestward motion is expected during the
next couple of days as Cristina is steered by a mid-level ridge over
northern Mexico. After that time, the weakening and shallower
system should turn westward steered by the low-level flow. The NHC
track forecast is once again nudged northward following the trend in
the latest guidance.
