In Mexico, a tropical disturbance early in the month brought flooding rains. The Government of Mexico reported that in the states of Puebla, Tabasco, Hidalgo, and Veracruz, there are 360 confirmed deaths and an estimated 315,000 people made homeless as a result of the recent flooding and associated landslides. Media and other sources estimated the number of deaths at 425.
Also, Cyclone 04B affected the states of Orissa, West Bengal, and Andhra Pradesh in India and left 56 people dead. Rice paddies were reportedly inundated, but damages were not yet assessed.
Hurricane Irene brought heavy rains from the Florida Keys northward to central Virginia in the U.S. Some places in eastern North Carolina and eastern Virginia received over 12 inches of additional rain, adding to the flooding problems. News sources reported that agricultural losses alone in Miami-Dade County, Florida due to flooding associated with Irene, could reach $100 million. Media have reported that between 5 and 15 deaths occurred in Florida and North Carolina. Total damages are now estimated at $800 million.
* Supercyclone hits eastern India on October 29th, 1999 *
A supercyclone with winds in excess of 160 mph swept in from the Bay of Bengal to hit the eastern state of Orissa on Friday, October 29th, 1999. This was the second tropical system to affect the region this month. Up to 15 million people have been left homeless by the storm, with the death toll estimated as high as 10,000. Phone lines and power supplies throughout the state of Orissa were also wiped out. Media reports have compared this cyclone to a 1997 tidal surge which killed thousands in neighboring Andhra Pradesh, and claim this is the worst cyclone to have hit the Indian Bay of Bengal region in three decades.
