RE: Hurricane season 2017 - SBH - 07-23-2017
Beautiful clear night right now for stargazing. There appears to be lightning off shore from whatever's left of Fernanda.

SBH - where are you looking from and in which direction is the lightning? I'm curious if I can see it. Thanks!

I'm off N. Kulani in Mt view and can see flashes almost due north.
Clear skies here.. so it's more noticeable. ( no thunder just flashes)
Weatherbug app says closest lightning strike about a hundred miles away.

Just checked and due north is consistent with satellite images. Thanks! There's some intense convection north of us:

Looks like Maui might be in for a night..( at the time of this posting anyway..)

Yes Tom the brightest part of the flashes was in the north but it lit up most of the sky. I first thought maybe neighbors were lighting leftover fireworks since the sky was so clear with really nice stars.

If you go here:

and then click on July 24th in the calendar you can see a nice video of the Keck Cosmic Cam picking up the lightning in the second half of last night. It moves in at around the 50-second mark at the right-hand side of the video (the NW).

In the East Pacific: Greg looks to be doomed, but Hilary and Irwin are predicted to interact with each other soon and we might see the Fujiwhara effect in play (where the two storms spiral into each other and potentially merge).
There's a nice article by Bob Henson describing the current situation:
https://www.wunderground.com/cat6/stormy-pacific-quiet-atlantic
"All three of the current systems—Tropical Storm Greg, Tropical Storm Irwin, and Hurricane Hilary (see Figure 1 above)—are projected to stay well out to sea over the next five days. Greg will be moving west toward increasing wind shear and drier air, and it will likely become a depression or remnant low by Wednesday. The more interesting dynamic will be the interplay between fast-intensifying Hilary (which could be a Category 2 or 3 storm as soon as Tuesday) and more slowly strengthening Irwin (likely to be a Category 1 by Wednesday). By midweek, Hilary is predicted to move within about 800 miles of Irwin, close enough to trigger Fujiwhara interaction, the process by which two tropical cyclones close to each other take on an aspect of rotation around a point in between. Because Hilary is expected to be a stronger cyclone at that point, its upper-level outflow will likely have an increasingly negative effect on Irwin’s strength."

Hurricane Hilary - Our question would be - Is there a Donald or Don to follow in the Atlantic ?

Mimosa - nearly! Tropical Storm Don formed in the Atlantic earlier this month but fizzled out...
