Tropical Storm "Dolly" developed from low pressure area on September 2, 2014, near Mexico's Yucatan Peninsula. At 12:00 UTC on September 2 the center was located about 145 miles (230 km) east-southeast of La Pesca, Mexico, moving west-northwest near 12 mph (20 km/h).
Dolly hit northern Tamiahua Lagoon, Veracruz, at 02:30 UTC on September 3 (21:30 local time on September 2) with winds of 46 mph (75 km/h) and gusts of 59 mph (95 km/h) generating severe weather and torrential rains which soaked Mexico's Gulf coast.
Authorities issued warnings of life-threatening flash floods and mud slides in mountainous areas.
Wednesday school classes were suspended in several municipalities along the Gulf coast.
At 03:00 UTC today, the center of Tropical Storm "Dolly" was moving over the coast of Mexico at 08 knots (9.2 mph/14.8 km/h). Minimum central pressure was 1002 mb.
Dolly is expected to produce rainfall amounts of 5 - 10 inches (127 - 254 mm) with isolated maximum amounts of 15 inches (381 mm) across much of Tamaulipas and Nuevo Leon as well as northern Veracruz and eastern San Luis Potosi through Wednesday evening.

Maximum recorded winds were 46.6 mph (75 km/h), wind gusts 59 mph (95 km/h). Norbert is moving north-northwest at 9.32 mph (15 km/h) and generating intense rainfall (2.9 - 5.9 inches/75 - 150 mm) in Baja California Sur, Sinaloa, Nayarit, Jalisco, Colima, Michoacan and Guerrero. Very strong rain (1.9 - 2.9 inches/50 - 75 mm) is generated over villages of Guanajuato and strong (0.9 - 1.9 inches/25 - 50 mm) over Zacatecas and Aquascalientes.
6.5 - 13 feet (2 - 4 meters) high waves and wind gusts of up to 31 mph (50 km/h) are generated along the coast of Michoacan, Colima and Jalisco.
Norbert is expected to move away from the southwestern coast of Mexico early Wednesday, and approach the southern tip of the Baja Peninsula on Thursday.
