 TROPICAL STORM JULIO DISCUSSION NUMBER   2
 NWS NATIONAL HURRICANE CENTER MIAMI FL       EP102014
 200 AM PDT MON AUG 04 2014
 
 Satellite images indicate that, although that the cyclone has a
 large area of associated deep convection, it is somewhat lopsided
 with most of the thunderstorms activity west of the center.
 However, Dvorak estimates from TAFB/SAB are both at 35 kt, and
 two ASCAT passes from a couple of hours ago indicate maximum winds
 of 35-40 kt.  The initial wind speed is, therefore, set to 40 kt in
 agreement with the ASCAT data.
 
 Only a gradual intensification of Julio is shown over the next 36
 hours due to a continuation of moderate northeasterly shear that is
 currently affecting the cyclone.  While there is some suggestion
 that this shear could abate after this time, there is enough
 uncertainty to only show steady strengthening.  At long range,
 the cyclone will be close to the typical sharp SST gradient over
 the eastern Pacific, as well as possibly a cold wake from Iselle,
 so no intensity change is indicated at that time.  The latest NHC
 forecast is only slightly higher than the previous one, between the
 latest model consensus and the Florida State Superensemble.
 
 ASCAT data show that Julio is moving westward at about 11 kt.  A
 strong ridge over the eastern Pacific is expected to steer the
 storm westward at a slightly faster forward speed for the next
 several days.  Julio should gradually gain some latitude by the end
 of the forecast period due to the orientation of the ridge, and
 model guidance has shifted northward at long range on this cycle.
 The NHC track forecast is also adjusted northward, but is still a
 bit south of the model consensus.
