TROPICAL DEPRESSION FOUR-E DISCUSSION NUMBER 3
WIKI-HURRICANES FORECASTING CENTER
5:00 PM HST TUE JUL 7 2015
Four-E looks better than evening, compared to earlier when it was as ugly as the USA's win over Honduras. Well-defined banding features have developed and the storm is slightly better organized. Estimates from the WHFC and TAFB at T2.5/35 knts, but SAB is at T1.5/25-30 knts. The intensity remains 30 knts but this is conservative.
The depression is currently heading west-northwest on the southwestern flank of a big mid-level ridge to the cyclone's northeast. This trajectory is expected to remain in place throughout 96 hours. Thereafter, interaction with an upper-level low, as well as the forecast shallowness of the system, may cause Four-E to turn more west-northwestward. The new track forecast is once again further south than the previous one since they models may be overdoing the interaction between this system and One-C, but lies more north than the ECMWF, but is further south than the GFSS.
