On July 28th, an area of low pressure developed near the Bahamas and tracked to the north-northeast. As it organized, it was upgraded to a tropical depression late on the 30th. By the 31st, the system strengthened into a tropical storm south of Nova Scotia. Chantal became extratropical late that same day as it moved over the cool waters of the north Atlantic towards Newfoundland. Peak intensity was 85 km/hr (43 knots or 50 mph) with a minimum pressure of 994 mb. More information on Chantal is available from the NOAA National Hurricane Center. |

| Cosme was first identified as an area of disturbed weather about halfway between Mexico and Hawaii in mid July. On the 15th, the storm was classified as a tropical storm with deep convection and an intensifying surface circulation. Under favorable conditions, Cosme became the first hurricane of the East Pacific season on the 16th. Soon after reaching hurricane strength, Cosme entered an environment of cooler waters and wind shear, which began to weaken the storm. On the 21st, Cosme passed approximately 185 miles (295 km) south of the Big Island of Hawaii bringing tropical storm gusts and heavy rain to parts of the island. While a hurricane, Cosme reported peak winds of 120 km/hr (65 knots or 75 mph) and a minimum central presure of 987 mb.

 Tropical Storm Dalila Track Map |
| On the morning of July 20th, a disturbance formed a few hundred miles south-southwest of the Gulf of Tehuantepec. By the 21st, this disturbance had developed into a depression. Despite moderate wind shear on the 23rd, convection began to deepen and the storm was upgraded to a tropical storm. Dalila remained a weak tropical storm and reached peak strength the afternoon of the 24th. Over the next several days, Dalila moved over cooler waters, which weakened the system. At peak intensity, Dalila had winds of 95 km/hr (52 knots or 60 mph) with a minimum central presure of 997 mb.

| In late July, an area of unsettled weather developed south of the tip of Baja California. As it moved westward, it developed an area of low pressure and some weak convection and was classified as a depression late on the 31st. This storm was upgraded to Tropical Storm Erick on August 1st, although strong wind shear prevented the storm from intensifying further and it dissipated on the next day. Erick reported peak winds of 65 km/hr (35 knots or 40 mph) and a minimum central presure of 1005 mb.
