Doomwatch, 20 July 2020 (Tropics and Pandemic)

There are a couple of weak tropical systems that the US National Hurricane Center is watching in the Atlantic and East Pacific, but nothing in the West Pacific this morning.   Here’s the view from GOES East of the Atlantic:

The only actual system (EP072020, East Pacific TD#7) is in the shadows as of 10am, off the Pacific Coast of Mexico, no threat to land.  The two “watch areas” have low formation probabilities; the mid-Atlantic invest area (AL99) perhaps a bit more, but still low over the next 5 days at 20%.  If you just need a spaghetti map, here’s an early look using the shallow (TABS) and mid level (TABM) steering currents, as well as some statistical models.

In viral doom, the data hasn’t really shifted that much over the last few days – as previously ranted, pandemics move slowly, with time scales in weeks.  Since we’re coming off a weekend and the data is catching up from that, I won’t post a plot, but the trends haven’t really changed much.  The precentage of people testing positive per test (the positivity ratio) as well as raw total positive patients showing up for treatment are still increasing far faster than anybody wants to see, mortality is up, not as much as the pessimistic predictions but worse than the optimistic scenarios.  Despite the Sturm und Drang, political posturing, and cultural gamesmanship, it is increasingly clear that masks outside the home are probably the best tool we have right now, especially if we want to resume something like normal lives.  So please just do it.

  1. I’d love to see your thoughts on the recent increase in positive percentages. I’d have thought it would take a lot of positives to move the percentage up and Georgia seems to have moved from a 9.something to 10.something rather quickly. My GPA never seemed to increase that quickly.
