| Bob Henson just posted a blog on the two systems: https://www.wunderground.com/cat6 Haven't read it yet, but skipped to: "At this early stage, it is far too soon to know how strong 91L might become, or how a trek across the Greater Antilles would affect its strength downstream, but the supportive environment and the track forecast imply we might be watching 91L for quite a few days to come." Here's an incredible sat view from CIRA: http://rammb-slider.cira.colostate.edu/ Wanted to have that at the top of the post. At the top of their main site ( http://rammb.cira.colostate.edu/ramsdis/online/tropical.asp ): "Announcement: Please visit out new web application, SLIDER, for every pixel of real-time GOES-16 and Himawari-8 imagery." TD8 is forecast to be a storm, but remain away from land. They say no threat to land, but there's often a rip current threat, though I don't know about a storm like this though. In 5 days it is forecast to be well NNW of the Azores: http://www.nhc.noaa.gov/refresh/graphics_at3+shtml/144700.shtml?cone#contents NHC had mentioned possibility of recon, but didn't in today's plan. No need on this one. Next up, 91L. It starts out around the same distance off Africa 99L started when it got designated. There's going to be a lot of time to watch it and a lot of varying model runs on this one. GFS has already been all over the place. Only a few models in the spaghetti plots so far: http://hurricanecity.com/models/models.cgi?basin=al&year=2017&storm=91&latestinvest=1 NHC started covering it in the Atlantic outlook at 2am EDT this morning with 0%/20%. Up to 10%/30% as of 2pm EDT this afternoon. "Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Sun Aug 13 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Eight, located several hundred miles southwest of Bermuda. 1. An area of disturbed weather located to the southeast of the Cabo Verde Islands is associated with a tropical wave. The wave is forecast to merge with a broad area of low pressure located southwest of the Cabo Verde Islands in a day or two. Environmental conditions are expected to become more conducive for development of this system later this week while it moves westward at about 15 mph over the tropical Atlantic. * Formation chance through 48 hours...low...near 10 percent. * Formation chance through 5 days...low...30 percent. Public Advisories on Tropical Depression Eight are issued under WMO header WTNT33 KNHC and under AWIPS header MIATCPAT3. Forecast/Advisories on Tropical Depression Eight are issued under WMO header WTNT23 KNHC and under AWIPS header MIATCMAT3.

There's also, when available, a lot of GOES-16 layers and 91L is just on the edge of the imagery. Bit blurry: https://realearth.ssec.wisc.edu/?products=G16-ABI-FD-BAND13-GRAD.100¢er=11,-28&zoom=5 That's just one of the full disk images, every 15 minutes. Lots of great GOES-16 sites: http://rammb.cira.colostate.edu/ramsdis/online/goes-16.asp http://rammb-slider.cira.colostate.edu/ (that cool view at the top of this post) https://weather.msfc.nasa.gov/cgi-bin/sportPublishData.pl?dataset=goes16abifulldisk&product=10p35um http://weather.cod.edu/satrad/exper/ NASA too: https://weather.msfc.nasa.gov/GOES/ First six options have GOES-16 imagery, CONUS and full disk. I haven't completed it yet, but I'm adding GOES-16 to the custom satellite page here at HurricaneCity. It just makes it easier to bookmark sat views with that viewer. The GOES-16 option will likely be under the "View Satellite" button when done. Since imagery is still technically in testing, it won't default to the sat, you will have to select it.
