Tropical Storm Boris (2014)
Tropical Storm Boris was a weak and short-lived tropical cyclone that brought rainfall to the Isthmus of Tehuantepec and surrounding areas in June 2014. The second named storm of the season, Boris developed from the interaction of a low-level trough and a Kelvin wave south of Mexico late on June 2. Initially a tropical depression, the system moved generally northward and strengthened into Tropical Storm Boris by midday on June 3. About six hours later, Boris peaked with maximum sustained winds of 45 mph (75 km/h) – indicative of a weak tropical storm. By early on June 4, interaction with land caused the storm to weaken, deteriorating to a tropical depression. Later that day, Boris degenerated into an area of remnant low pressure, before fully dissipating over the Gulf of Tehuantepec on June 5.
As Boris approached land, tropical cyclone warnings and watches were issued, school classes were canceled, and evacuations occurred in Southwestern Mexico and portions of Guatemala. The precursor to Boris and the storm itself brought heavy rainfall to area. In Mexico, overflowing streams left minor damage in Chiapas; four people were injured when a house partially collapsed. One death was reported in the country when a tree fell at a high school in Xalapa. Flooding in Guatemala forced 198 people to flee their homes. A mudslide caused five deaths and injured seven others. Overall, 20 mudslides were reported, damaging 13 roads. Additionally, 223 homes were damaged, including 11 severely. More than 5,000 people were left isolated in Quetzaltenango after a portion of the main road to the city was inundated by water.
==Meteorological history==
Early on May 30, the National Hurricane Center (NHC) began monitoring an area of disturbed weather, perhaps in connection to a tropical wave, several hundred miles south of southeastern Mexico for tropical development within a five-day period. Within an increasingly favorable environment for formation, the disturbance was assigned a medium chance of becoming a tropical cyclone within the next 48 hours later that day, and a high chance of development on May 31 as it became increasingly better organized. In conjunction with a ship observation and satellite intensity estimates, the disturbance acquired enough organization to be deemed a tropical depression at 2100 UTC on June 2.
Over the subsequent hours after its formation, little change in organization was noted, with multiple low-level centers rotating within a broader circulation positioned on the south side of the deepest convection. However, a pair of Advanced Scatterometer (ASCAT) passes early on June 3 revealed sustained winds just above the tropical storm threshold, and the depression was subsequently upgraded to Tropical Storm Boris. Despite initial forecasts of several days over water,〔 the center of circulation moved quickly northward in response to an upper-level low west of the system, and the bulk of Boris's deep convection moved ashore near Chiapas, Mexico around 0600 UTC on June 4. However, the cyclone's northward motion slowed, and the low-level circulation remained offshore, failing to ever make landfall. Thereafter, the system degenerated into a trough of low pressure about 80 mi (130 km) east-northeast of Salina Cruz, Mexico.
