Tropical storm Dolly dissipated quickly after coming ashore yesterday in eastern Mexico but dropped heavy rain in some areas near the Gulf coast. At the same time tropical storm Norbert was approaching from the west and contributing to rainfall near Mexico's Pacific coast. TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) data for the period from August 28 to September 4, 2014 were used in the analysis shown above. The approximate past locations of the tropical cyclones at 0000Z and 1200Z are shown overlaid in red on this analysis. The heaviest rainfall totals were found

Tropical storm Dolly is dissipating after coming ashore in eastern Mexico late yesterday evening. The TRMM satellite flew over tropical storm Dolly early on September 3, 2014 at 0844 UTC ( 3:33 AM CTD) providing data used in the image above. TRMM's Microwave Imager (TMI) collected with that orbit showed that Dolly was dropping light to moderate rainfall near the dissipating storm's center of circulation. Moderate to heavy rainfall, falling at a rate of over 30 mm ( about 1.2 inches) per hour, was shown in a strong band of showers moving ashore north of Dolly's center. The TRMM satellite had a
