Currently en República Dominicana — 27 de septiembre: Vigilamos el Atlántico por el tránsito de dos sistemas atmosféricos

El tiempo, currently.
Vigilamos el Atlántico por el tránsito de dos sistemas atmosféricos
La Tormenta Tropical Philippe avanza en el Atlántico central con trayectoria hacia el norte de las Antillas Menores, donde podría llegar entre viernes y sábado; al momento de acercarse a nuestra región podría empezar a debilitarse hasta ser una depresión. Los modelos de pronóstico prevén la incidencia indirecta del sistema atmosférico el domingo.
Mientras que damos seguimiento a un disturbio ubicado en el Atlántico oriental con potencial de convertirse en la Depresión Tropical 18. Este fenómeno debe ser vigilado por su trayectoria carcana a las Antillas Menores.
En las próximas 24 horas continuará el panorama meteorológico en República Dominicana dominado por una vaguada y los vientos húmedos. En la tarde se esperan lluvias hacia el sur, sureste, Cordillera Central, noroeste y zona fronteriza.
What you need to know, currently.
With drought affecting broad swaths of the Mississippi River valley, river levels have dropped so low that saltwater from the Gulf of Mexico is creeping upriver in the Mississippi itself. At its current rate of progression, the Mississippi will turn too salty for water treatment plants at New Orleans to produce drinking water in just a few weeks.

Since saltwater is more dense than freshwater, the saltwater is actually moving upriver along the riverbed — within the river itself. Federal engineers that maintain the river channel have built a partial dam designed to slow the saltwater’s upstream progression, and increasingly extreme measures will need to be taken once the saltwater reaches New Orleans — like transporting freshwater by barge, and hastily building a water pipeline to the city.
Similar events happened in 1988, 1999, 2012, and again last year — but this one seems especially severe.
As global warming melts ice worldwide, sea level rise will make problems like this worse not just for Louisiana, but all coastal cities worldwide.
