Another AoI has been marked behind 95L with 0/20 chances right now.
The Atlantic MDR area of interest is a tropical wave that is expected to move off the coast of Africa tomorrow night according to the NHC. NHC in the most recent Tropical Weather Outlook upped the 7 day chances to 40% so it is now 0/40.

After 45 freaking warnings and 11 days, Krosa is finally done for:
————————————————————
Krosa (Japanese Typhoon Number 9) is located 1604 km east-northeast of Misawa, Japan, and has tracked east-northeastward at 41 km/h (22 knots) over the past 6 hours. Minimum central pressure at 03/18:00 UTC is 983 hPa. Maximum significant wave height is 6.7 meters (22 feet).
Infrared imagery shows an elongated and heavily sheared system, with nearly fully exposed low-level circulation center (LLCC) and remaining associated convection to the east. Additionally, an older MetOp-B ASCAT image showed highly asymmetric wind field, with higher intensities along the southern portion of the circulation.
The system is currently becoming extratropical, due to crossing into the baroclinic zone to the north. Krosa is positioned poleward of a western extension of a subtropical jet.
Assessment is supported by GFS and ECMWF phase cyclone diagrams. Additionally, very cold (17–18°C) sea surface temperatures and increasing wind shear are creating an increasingly hostile environment for tropical development.
Model guidance is in strong agreement in regard to the track and intensity, resulting in high confidence of the official JTWC forecast.
This is the final warning on this system by JTWC. The system will be closely monitored for signs of regeneration.
Warning Number 45. Information provided by the Joint Typhoon Warning Center (JTWC).

Invest 95L became Tropical Storm Dexter late last night. It is expected to move out to sea and not affect any land areas.
We got Tropical Depression 14W overnight from the High Chance WPAC invest, but the storm is already dead.
Invest 90E became Tropical Depression Eight-E last night as well. It could pass north of Hawaii as a weakening Tropical Storm. Next name in the Eastern Pacific is Henriette.

Well for once what seemed like a junkie actually might form after all.
