Part of the 2007 Pacific hurricane season

Tropical Storm Erick was the eighth tropical cyclone and fifth tropical storm of the 2007 Pacific hurricane season. Erick originated from a tropical wave that moved off the coast of Africa, traveled westward across the Atlantic Ocean, and emerged into the Eastern Pacific Ocean without any further development. The wave spawned a small low-pressure system on July 28, which matured into a tropical depression later that day despite strong wind shear in the region. The depression intensified into a tropical storm, and received the name "Erick" while continuing its westward track. However, the shear prevented the storm from intensifying further, and broke up the storm's structure within a few days. The cyclone weakened to a tropical depression and degenerated into a remnant low shortly after. Because the storm remained far out at sea, no damage was reported in association with Erick.

Meteorological history

In mid-July 2007, a tropical wave emerged from the coast of Africa and traveled westward across the Atlantic Ocean. On July 22, the wave passed through the Lesser Antilles with some strong, yet disorganized thunderstorm activity. The wave crossed Central America three days later into the Eastern Pacific Ocean, where it later spawned a small low pressure area. Wind shear prevented tropical cyclone development for a few days, leaving the area of convection, or thunderstorms, separated from the low. The convection began to form closer to the center of the storm. On July 31, the National Hurricane Center designated the low as Tropical Depression Eight-E while the system was located 1,060 miles (1,700 km) southwest of the southern tip of Baja California. The convection remained concentrated on the western edge of the storm because of the shear and the presence of dry air. Owing to higher Dvorak intensity estimates, the NHC upgraded the depression to Tropical Storm Erick at 0000 UTC on August 1. Upon its upgrade, Erick attained peak winds of 40 mph (65 km/h) and a minimum central pressure of 1004 mbar (hPa; 29.66 inHg).

The wind shear did not relent, and Erick maintained a disorganized structure with a lack of banding features. As a result, the exact position of the center was difficult to locate. The storm tracked westward at around 10 mph (17 km/h) under the steering currents of a mid-level ridge to its north. Later on August 1, the strong shear separated the center from the waning area of thunderstorm activity, indicating that the storm was deteriorating. Erick weakened back to a tropical depression on August 2, only 24 hours after it became a tropical storm. The low-level center became elongated and ill-defined; the depression continued to weaken quickly and degenerated back into a tropical wave on August 2, thousands of miles from land. A weak low reformed along the wave, although it did not reorganize into a tropical cyclone as it entered the North Central Pacific. On August 5, the low-level remnants of Erick passed south of Hawaii, although they caused no effects on the islands. The low dissipated fully on August 8.

Impact

Because Erick remained "very far away from everywhere", no effects, property damage or fatalities were reported; no ships recorded tropical storm-force winds, and no tropical cyclone warnings and watches were issued. Throughout its course, Erick posed a threat only to shipping lanes.
