Looks quite a bit organized to be ignored

An area of disturbed weather has persisted near the International Date Line between Wake Island and Midway Atoll [no invest area is current for this system]. This disturbance is associated with a 1009 hPa area of low pressure and an active surface trough. Shower activity associated with the disturbance has increased in organization and coverage during the past 24 hours, although recent ASCAT and ScatSat-1/OSCAT passes do not indicate a well-defined circulation. Conditions are currently conducive for further development of this system and a tropical depression could form within the next couple of days as it moves slowly northwestward over open waters. By Monday, upper-level winds will become less favorable for development.

As part of my uofficial 1979 Typhoon Season reanalysis, I analyzed Hope's landfall at 105 kt/940 mb, although I did not use any land data with this analysis. I'm curious if any pressure readings in particular exist at or near the landfall point which I can use to refine my estimate.

The large-scale global tropical pattern has been fairly stationary over the past week, reflecting conditions similar to a West Pacific intraseasonal event. Widespread convection continues across East and Southeast Asia and across the Pacific, and propagation has had more of a northward component than an eastward one. The RMM-based MJO index has been somewhat erratic, but has remained outside of the unit circle over the past few days in Phases 6 or 7. The CPC velocity potential based MJO index also indicates an enhanced (suppressed) convective phase over the Pacific (Western Hemisphere), which is similar to the position of the MJO during mid-July. Analyses of low-level zonal wind anomalies reflect a persistent regime of weakened trade winds across the equatorial Pacific, part of which is due to tropical cyclone activity, but may also indicate a shifting atmospheric base state towards El Nino conditions. Additionally, a robust, convectively coupled Kelvin wave is currently crossing the Maritime Continent to the West Pacific. Dynamical model MJO index forecasts generally depict weak to no MJO activity over the next two weeks. The GEFS shows a weak-amplitude signal crossing the Western Hemisphere rapidly, with an intensification over the Indian Ocean by the end of Week-2. This may be due to the Kelvin wave. The ECMWF shows no MJO activity whatsoever during the forecast period, but many ensemble members run at the monthly time scale depict a return of enhanced West Pacific activity during late August. Based on both recent observations and the dynamical model forecasts, the MJO is anticipated to remain weak during the upcoming two weeks, and a robust Western Hemisphere event transitioning to the Indian Ocean, which could yield more favorable conditions for Atlantic tropical cyclone development, seems unlikely.
During the forecast period, continued West Pacific tropical cyclone development is favored.
There are two areas of potential development over the Northwest Pacific during Week-1, one east of the Philippines, and a second area near or just east of Guam. Confidence in formation within either of these regions is low to moderate, but given the presense of a broad trough in the region, a large moderate confidence forecast shape covering both regions was included in the outlook. During Week-2, a quiet pattern is anticipated to continue over the East Pacific and Atlantic basins, while a moderate potential for tropical cyclone development across a broad portion of the Northwest Pacific in the vicinity of Guam continues.
