The reason this area is key is because it hosts the best wind shear and instability.

That’s because it tends to reduce wind shear in the tropics, enabling hurricanes to grow in strength, and keeps Atlantic Ocean water warm, which helps fuel storms.

“This is because of the anticipated onset of La Niña, which suppresses wind shear, and the anomalous lingering warmth that’s expected to remain in the tropical Atlantic and in the Caribbean,” Grow Cei said.

The study includes a four-page list of proposed seismic upgrades, such as adding two-foot-thick reinforced concrete shear walls extending from the foundation to the roof, putting supportive “jackets” around the existing columns, and adding a variety of reinforced concrete beams and flanged buttress walls.

“Landslide movement continues to manifest at the ground surface in the form of scarps, fissures, grabens/sinkholes, tensional cracking, shear zones and thrust features,” the city’s latest report said.
