Tropical Storm Emilia was the sixth tropical depression and fifth tropical storm of the 2006 Pacific hurricane season. A low-pressure center formed on July 16 in the Atlantic basin and became a storm in the Eastern Pacific basin. The low was able to strengthen into a tropical depression and then into a storm the next day. Operationally, the storm was measured to have peaked at 70 mph (115 km/h). However, this was decreased to 65 mph (105 km/h) in post-season analysis. Emilia affected Mexico's mainland and the Baja California peninsula before degenerating into a remnant low on July 28, dissipating three days later.[1][2][3]

[edit] Storm history
A tropical wave moved off northern South America and entered the Eastern Pacific basin on July 16.[4] The wave started showing signs of organization on July 18 and the National Hurricane Center forecasted that it would become a depression in the next few days.[5] However, later that day, the appearance that the system would become a depression began to diminish.[6] By July 19, thundershower activity returned and the earlier forecast also reappeared.[7] On July 20, a surface low-pressure system developed along the wave axis south of Acapulco, Mexico. The low-pressure area moved northwestwards and became more organized. Due to this, the National Hurricane Center upgraded the surface low into Tropical Depression Six-E on July 21, 350 nm (405 mi, 650 km) south-southwest of Acapulco.[4]
After turning northwestwards, banding features became more developed and better defined, thus strengthening into Tropical Storm Emilia on July 22.[4] Tropical Storm Emilia moved in alternated directions around a southwestern periphery of a subtropical ridge. Around 0600 UTC July 22, Emilia moved within 150 nm (175 mi, 280 km) of Manzanillo, Mexico, possibly producing tropical storm winds. Emilia reached its first peak intensity of 65 mph on the night of July 23. An increase in vertical wind shear caused Emilia to weaken in the next 24 hours.[4]
Emilia began to re-intensify on July 25 as the upper-level wind shear relaxed and reached its second peak intensity of 65 mph on the same day.[4] Later on July 25, Emilia passed within 50 nm (60 mi, 95 km) southwest of Cabo San Lazaro. By July 27, Emilia had entered cooler sea surface temperatures and weakened to a tropical depression at 1200 UTC. Emilia degenerated into a remnant low on July 28. The low moved westward slowly and turned to the north on July 30. Finally, the remnant low dissipated on July 31.[4]
There was a chance Emilia could intensify into a Category 2 hurricane on the Saffir-Simpson Hurricane Scale, but this did not occur. By July 24, the chances of Emilia reaching hurricane status had diminished.[8][9]
[edit] Preparations and Impact
Several tropical storm watches and warnings were released in accordance with Tropical Storm Emilia.[4] The first was issued as a Tropical Storm Watch from Manzanillo to Cabo Corrientes on July 22, which was discontinued the next day. On July 25, a Tropical Storm Watch was issued for Buena Vista to Bahía Magdalena. This was upgraded to a Tropical Storm Warning six hours later, but discontinued on July 26. A new warning was issued for Cabo San Lucas to Punta Eugenia on July 26. Nine hours later, it was extended to Santa Fe and Puerto San Adresito. All watches and warnings were discontinued on July 27.[4]
Rainfall totals were reported to be 3-5 inches across the southern portion of the Baja California peninsula, with a peak of 5 inches in Cabo San Lucas. However, higher unreported rainfall could have occurred in the Peninsula's mountains. Tropical storm force winds were reported on the southern tip and southern coast of the peninsula. Wind trajectories suggest that tropical storm force winds may have occurred on the Mexican Mainland near Manzanillo and Cabo Corrientes.[4] The tropical storm on July 26 was able to drop rain on the northern Baja Peninsula and cooled down temperatures.[10] It rained for 1½ days in Baja California, sparking gusts reaching up to 75 miles per hour. Streets flooded and sewer systems became unusable due to flooding. Some people lost power as flooding destroyed power lines.[11] Emilia moved mud and gravel onto the main street in Cabo Centro, near the Marina. Some roads got messy from the lack of pavement on the road.[11]
Minor flooding occurred in Cabo San Lucas, with some damage to buildings and above-ground utility lines. Several marinas reported minor wave damage, resulting in their two-day closure. There were no reports of casualties as a result of the passage of Tropical Storm Emilia. Despite this, 100 people were forced to stay in government shelters due to the floods. Rains from the remnants of Emilia helped with a wildfire in Cleveland National Forest, and helped to alleviate a two-year drought in Baja California Sur.[12][13][14] High pressures and moisture affected parts of Nevada, Utah and Arizona on July 27, as Emilia traveled up the Baja coast.[15]
This was the sixth use of the name Emilia in the Eastern Pacific basin, which was previously used in the 1978, 1982, 1988, 1994 and 2000 Pacific hurricane seasons. As no storm names were retired in Spring 2007, the name Emilia is to be used in the 2012 season.
