 HURRICANE JIMENA DISCUSSION NUMBER  11
 NWS NATIONAL HURRICANE CENTER MIAMI FL       EP132015
 200 AM PDT SAT AUG 29 2015
 
 Jimena is an impressive hurricane on satellite imagery tonight with
 a symmetric central dense overcast, warm eye, and fanning cirrus
 outflow in all quadrants.  The current intensity estimate is 130 kt,
 a blend of the latest Dvorak values from TAFB, SAB and UW-CIMSS.
 While large-scale environmental factors are still favorable for
 further strengthening this weekend, Jimena will likely go through an
 eyewall replacement cycle during the next day or so, which can cause
 fluctuations in intensity that are impossible to forecast. However,
 Jimena is likely to remain a very powerful hurricane for the next
 several days.  A slow decay is forecast by late Sunday since oceanic
 and atmospheric conditions will only gradually become less
 conducive, with a more pronounced weakening expected by mid-week.
 The new forecast is primarily a blend of the previous one and the
 statistical models in the first two days, with a heavier weight on
 the intensity consensus at days 3 to 5.
 
 The initial motion estimate is 270/8.  Jimena's heading should
 become west-northwestward later today and continue in that general
 direction for the next several days while it moves around the
 subtropical ridge.  As Jimena nears a break in the ridge around
 140W, a significant decrease in forward speed is likely after 96
 hours.  The track guidance remains tightly clustered, and the new
 track forecast has been moved only slightly southward, similar to
 the adjustment made on the previous advisory.
