"Amanda" forms as first tropical storm of 2014 Eastern Pacific hurricane season

2014 Eastern Pacific hurricane season officially started on May 15, 2014. A week later, its first tropical depression was born southwest of Mexico. On May 23rd the system organized and strengthened into the first tropical storm of the season and was named "Amanda".

At 15:00 UTC today Amanda was centered near 10.9 north latitude and 108.4 west longitude, about 1 000 km (620 miles) south-southwest of Manzanillo, Mexico, moving west-northwest at 7 km/h (5 mph). It had a minimum central pressure of 1005 millibars.

At the time, Amanda's maximum sustained winds had increased to 65 km/h (40 mph). Tropical-storm-force winds extended outward up to 55 km (35 miles) from the center.

The NHC discussion indicated that forecasters there expect Amanda to reach hurricane strength in about three or so days.

At 22:59 UTC on May 21 the Tropical Rainfall Measuring Mission (TRMM) satellite passed over System 92E, which will later strengthen into Tropical Storm Amanda.

TRMM's Precipitation Radar (PR) data were used to create a 3-D view of System 92E's rainfall structure and revealed a few strong thunderstorms reached altitudes of 16.5 km (about 10.2 miles).

These tall thunderstorms are often a sign that a tropical cyclone is forming or strengthening. Within twenty-four hours. (Goddard)
