Hurricane Teresa was a destructive and slow-moving Cantalle hurricane, and was the last hurricane of the extremely active and deadly 2022 hurricane season. Teresa developed from an area of disturbed weather which was first monitored over the Masse Islands on September 18th. The system grew a broad area of low-pressure on September 19th, and was designated as a tropical depression late that day. Early the next day on September 20th, the depression made landfall at Lillestola, and subsequently strengthened into Tropical Storm Teresa that afternoon. Moderate northwesterly shear prevented significant intensification for the first two days, but convection continued to grow towards the center and Teresa slowly intensified. On September 23rd, a center reformation into the center of the convection occurred, and data from a hurricane hunter reconnaissance aircraft showed that Teresa rapidly intensified into a strong Category 1 hurricane. However, an increase in wind shear and upwelling of colder waters halted the intensification and Teresa weakened slightly on September 24th before turning slowly northeastward up the Northern Cantalle Islands. Despite this increase in wind shear, it unexpectedly re-intensified, reaching Category 2 status early on September 26th over Saint Astaba and Beck, before making landfall on the mainland at peak intensity on September 28th, near Colinada, Lyonnais, Zamastan, with maximum sustained winds of 110 mph (180 km/h) and a minimum central pressure of 965 millibars (28.5 inHg). The storm rapidly weakened after landfall, before dissipating over Lake Greening.
Numerous watches and warnings were issued in anticipation of the imminent approach of Teresa and several coastline settlements were evacuated. In Lyonnais, heavy rain led to localized flash flooding while the rest of the peninsula saw continuous shower and thunderstorm activity due to asymmetric structure of Teresa. The area between Irocarres and Kenzieland took the brunt of the storm with widespread wind damage, storm surge flooding, and over 20 inches (510 mm) of rainfall in the first 24 hours and over 30 inches in 48 hours.
