Hurricane Erick Winds: 95 kt
Pressure: 964 mbar
Advisory 18 / 2:00 PM PDT Wednesday, July 31, 2019

Erick is doing well for itself this afternoon. Although the hurricane's eye is obscured on satellite, the central dense overcast is symmetrical. In addition, the inner core looks better this afternoon than it did last night, when it appeared we were on the verge of rapid weakening. A consensus of satellite intensity estimates supports an intensity of 90kt, but an average of current intensity values yields 100kt. The initial intensity remains 95kt as a compromise.

Upper-level winds have increased over the past 24 hours, but they remain at marginal levels for now. In addition, ocean temperatures remain sufficient at 27C. Therefore, only slow weakening is forecast in the next 24 hours. Thereafter, while water temperatures will actually be on the increase, so too will wind shear. In fact, upper-level winds are expected to exceed 40kt on days 2 and 3. Thus, rapid weakening is forecast, and Erick is expected to become a remnant low about 96 hours from now, if not sooner.

The hurricane is moving west-northwest, steered by stout mid-level ridging to its north. Over the next 72 hours, a west to west-northwest course will continue as the mid-level pattern remains constant. Thereafter, though, a weak mid-level trough should induce a weakness in the ridge to Erick's north, allowing the weak system to move between west-northwest and northwest.
