A picture is indeed worth a 1000 words. The Pacific is just on fire with tropical activity. The rest of the world? Not so much. El Nino starts in the Pacific. The rest of the oceans (and the world) should take notice.

#Lala is on the verge of becoming a major hurricane out in the Central Pacific. It may make a run at category 4 status. NOAA researchers spread out across the Papahānaumokuākea Marine National Monument will likely be evacuated in the coming days.

Still some time for #Lala to strengthen as it approaches the Big Island. Kerry Emanuel's max wind potential product (mainly based on available energy from SSTs) gives the storm a hypothetical pathway to category 1 or low end category 2 status

More aircraft recon scheduled for tomorrow for still the still unnamed storm. Meanwhile, the system to the east has officially reached tropical depression status. Scratching my head a bit

It's rather telling that both current recon missions into PT-01C are focused on the environment around the storm. The system is ready to pop, but the surrounding environment remains hostile.

July was the hottest month on record in the lower 48. And it was tied (July 2024) for the hottest July on record globally. Global ocean temps also set a new monthly all-time record. The world is roasting. But California? Not so much. www.sfchronicle.com/climate/arti...

July’s heat records piled up worldwide. California stood apart

The planet tied its hottest July on record and the oceans and Lower 48 set new heat records. California was a bit different.

#Genevive is the proverbial canary in a coal mine. This storm is making a run a Category 5 status. Thankfully, it will die in a few days with no threat to land. But if there was ever a sign showing that the Pacific Ocean is loaded with heat, this is it.

New story this morning: A Chronicle analysis of historical hurricane data found Hawaii was nearly 2.5 times more likely to see a named tropical system pass close enough for impacts during summers preceding a strong El Niño. (🧵) @sfchronicle.com www.sfchronicle.com/weather/arti...

Hawaii is entering a dangerous stretch as a powerful El Niño builds

A warm Pacific and an impending strong El Niño could open the storm track to Hawaii, especially over the next few months.

Keep an eye on hurricane #Fausto. Surprisingly high confidence in a storm track aimed directly at Hawaii early next week. Fausto will likely be a borderline tropical storm by that point, but will still pose a danger to the islands.
