Hurricane Genevieve Rapidly Strengthens to a Category 4 in the East Pacific; Tropical Storm Warning For Baja California #Hurricane #Genevieve #Category4 #EastPacific #BajaCalifornia #Mexico
Hurricane Genevieve rapidly intensified off the Pacific coast of Mexico and it could bring tropical storm conditions to parts of Baja California.
Genevieve became the second Category 4 hurricane of the eastern Pacific season on Tuesday. Its maximum sustained winds increased from 75 mph to 130 mph in the 21 hours ending 6 a.m. MDT on Tuesday. That easily met the rapid intensification criteria for a hurricane, an increase in wind speed of at least 35 mph in 24 hours or less.
The forecast track for Genevieve takes the center of the hurricane just west of the southern tip of Baja California, including Los Cabos, later Wednesday through Thursday. This track could spread at least some bands of rain and gusty winds into the southern Baja during that time.
A tropical storm warning has been issued for the southern part of Baja California, including Cabo San Lucas. The National Hurricane Center says tropical storm conditions (winds 40 mph or greater) are expected in the warning area by Wednesday afternoon and could continue into Thursday, particularly over higher terrain areas.
Genevieve could also spread some locally heavy rainfall into the southern Baja. Rainfall totals of 1 to 4 inches are possible in some areas.
High surf from Genevieve is also expected to spread from the southern coast of Mexico to Baja California through midweek. Eventually, swells generated by Genevieve could reach Southern California by this weekend.
There is also a chance Genevieve could send a surge of moisture into the Southwest late this week or over the weekend. That might lead to an uptick in thunderstorm chances over the higher terrain of southern California and Arizona.

An asteroid just made the closest fly-by of Earth ever recorded… and nobody saw it coming #Asteroid #Earth
A car-sized asteroid just skimmed past Earth in the closest space rock fly-by ever recorded. And none of our planetary defense systems saw it coming until it had already passed by.
Asteroid 2020QG whizzed past Earth at a distance of less than 3,000 kilometers, meaning it came closer than the vast majority of commercial satellites that orbit Earth. The remarkably close shave means the space rock jumps straight to the top of Earth’s close calls with asteroids. This is despite the database stretching back over 100 years.
Astronomers at the Palomar Observatory in California first spotted the asteroid six hours after it flew by Earth. Observations suggest the space rock came closest to Earth when it flew over the Southern Hemisphere just after 4am Universal Time on Sunday.
Experts say 2020QG posed little risk to Earth as it would likely have been almost entirely burned up by the atmosphere had it been on a collision course with our planet.
However, it again highlights the importance of asteroid detection systems and that our planetary defenses need to be bolstered, in case more serious threats stray into Earth’s path in the future.
A stark example of this is the undetected Chelyabinsk meteor which exploded above Russia in February 2013. The comet was just 18 meters in diameter, but was still sizable enough to cause significant localized damage including blowing out thousands of windows.
Another example came in December 2018 when an undetected asteroid that was 10 times more powerful than the bombs dropped on Hiroshima and Nagasaki broke apart over the Bering Sea.
