July 31 Atlantic Evening Tropical Bulletin 9:30 PM

Discussion... Organization of tropical system in the Atlantic comparable to a disaster zone.
System is very unorganized, with a few clusters of strong convection. Strongest cluster is on the western portion of the system (big blob in the middle of the screen).
We do expect this system to potentially develop soon, but this organization is not favorable for a tropical depression to form ATTM.

Strong Storms in South Dakota/North Dakota

We're monitoring some strong to severe storms in South Dakota moving into North Dakota. The storm by Bison, SD is being monitored more closely, as it is producing multiple warnings and also has a pink core. What a pink core indicates is that the storm is very healthy and strong. It also could be an indicator or how the storm could stick around for quite a while.
Northern Plains infrared imagery indicates cloud tops are extremely tall. Checking our advanced radar, it looks like the storms have cloud tops scanned to at least 65,000 feet- quite a spectacle. Storms will continue to blossom in the area of North Dakota back into South Dakota. If these first cells are a sign of what's to come, this certainly will be a long night.

Notice

We were able to hook up to a network that enables us to post on the blog.
You will receive more detailed but still limited posts from us in the coming days.

July 31 Atlantic Tropical 930 Am Bulletin

A system in the atlantic ocean remains at a very high potential for formation as of 930 am. We do not have good computer access, so we cannot upload images.

July 31: Tropical Depression FIVE (East Pacific Ocean) 8:00 AM Bulletin


Tropical Depression FIVE has formed in the East Pacific.
This storm is more on the smaller side according to the infrared imagery, but it could be because I am not looking at what could be the 'arms' of the storm.
Tropical Depression FIVE will become a tropical storm and move parallel to land. It will stay far away from land. The storm will eventually strengthen into a Category 1 hurricane, but that appears the worst it will strengthen to.

Ensemble plots of track and intensity indicate that information above is right on both counts.
