#Março de 2021 é o mês mais letal da #pandemia. Os 17 dias em que mais pessoas morreram de #covid foram neste mês. É o que indica análise preliminar do Ministério da Saúde, com dados de mortes por #datareal contabilizados até 22 de março.

So #Laura's current position has been repeatedly south of what models forecast. Let's examine why that might be the case.

Look at this GFS trend in upper-level PV (shaded) and 850 vorticity valid at 00Z. Note how #Marco gets stronger with each forecast, and Laura dips south.

As #Marco is (correctly) shown to be stronger, latent heat release increases, and contributes to the upper level ridge to the north of #Laura (east of Marco). You can see this by the steady increase in deep blues (low PV values) with a stronger Marco. (same loop here as above)

That could be a coincidence, but now let's use some amusingly poor #HWRF parent domain forecasts to diagnose this impact. As above, here's a model trend in the outer domain of #Laura's forecasts, which only model #Marco on the lower-res parent domain (and poorly, I might add).

Le Golfe du Mexique pourrait être touché simultanément par deux #ouragans la semaine prochaine. Situation très rare, peut-être inédite.

Les deux tempêtes tropicales devraient devenir des ouragans de catégorie 1 (#Laura et #Marco) avant de toucher les côtes américaines.
Les plateformes pétrolières du Golfe du Mexique vont devoir être arrêtées par précaution mais le risque de dommage est limité.
#pétrole #risque

Marco devrait toucher les régions pétrolières et gazières des environs de Houston.
Avec un ouragan de 1ère catégorie, le risque de dommages durables est faible mais pas inexistant sur les raffineries (inondation, perte d'alimentation électrique...).

Two tropical depressions now forecast to simultaneously hit the US as hurricanes Laura and Marco, on Tuesday evening.

There's Laura:

It now looks like Marco will reach Texas on Tuesday, as a tropical storm. Laura could hit neighboring Louisiana as a hurricane a day later, after moving over Hispaniola and Cuba as a tropical storm.
