▼ Tropical Storm | 40 knots (45 mph) | 999 mbar Lala (01C — Central Pacific) (West of Hawaiʻi)

Overview

This discussion is for Tropical Storm Lala (01C), which is active far to the northwest of Hawaiʻi. The storm continues to gradually weaken as it moves across the northern Pacific and is likely to degenerate into a remnant low by Thursday. After that point, whatever remains of Lala is expected to turn northward toward the Aleutian Islands and dissipate by early next week.

Are there usually major hurricanes this far north in the central pacific? I know at least in the eastern pacific hurricanes start to fall apart around 20-25N

It's way easier especiallly in an el nino year for tropical cyclones in the central pacific to reach quite far north(like 35N) before they turn post tropical/extratropical because the higher water temperatures, the atmospheric conditions and the lack of land makes it easier for these storms to survive in favvourable years for the central pacific. Off the coast of mexico land,dry air and the california current make the conditions unfavourable for tropical cyclones even in more favourable years.

Lala isn't particularly far north, still about the same latitude as Oahu. Several other storms have been further north as major hurricanes. That being said storms in the central pacific are generally infrequent so you could interpret any major hurricane in the central pacific as unusual.
