There is no fruit involved in the process of dumping a "pineapple express" on the west coast.
There is heavy rain and snow visible in the sky on Thursday.
Much of California is under a flood watch because of the severe droughts and fires of the next few years, according to the National Oceanographic and Atmospheric Administration.
The state is under an atmospheric river, which is a thin region of the atmosphere that ships water outside of the tropics. Exports from Hawai'i are one of the effects.

The "Pineapple Express" is an atmospheric river that brings water from the tropics to the west coast.
Weak systems that provide beneficial rain or snow are crucial to the water supply, and not all atmospheric rivers cause damage. In the western United States, atmospheric rivers are closely tied to both water supply and flood risks.
The National Weather Service has some travel advisories for local residents who may be in the path of flooding.
Good morning #BayArea and #CentralCoast from your day shift at the NWS forecast office.Got a deep tropical moisture tap setup to take aim at our region on #NYE. Plan ahead, add extra time to travel, stay home if you don't need to go out.#cawx pic.twitter.com/ZfqZgKxcbWDecember 29, 2022

Weather forecasts, disaster response, and long-term climate monitoring are all provided by the satellites of both NASA and the National Oceanographic and Atmospheric Administration.
Information gained from the fleet can be used to make forecasts. Flood warnings can be given as early as a week in advance if atmospheric rivers are spotted.
