Here's a pretty cool view of Octave (furthest west) getting pulled into the orbit of Priscilla (was a big Cat 2 hurricane) and now Raymond forming to the east.

It's a busy early October in the tropical Eastern Pacific with the O, P, and R cyclones/remnants in close proximity to one another with lots of Fujiwhara interactions going on!

Fun fact: Due to lack of available names beginning with Q, that letter is skipped when naming storms (U & Z too) #COWX

Tricky forecast today due to developing Denver Cyclone east of DIA, clearly visible on satellite this morning. Actually seeing some sunshine in Boulder as it settles in, but we don't look for that to continue for too long... Low clouds should eventually sock back in #COWX

Yep that area is 8500-9500 feet

💦 0.57" of rain overnight. A good drink as we move towards snow season in the Front Range!

Not sure how the NWS avoided the big, yellow, non-partisan banner message on their website regarding the "Radical Left Democrats" shutting down the government, but good job! #COWx
