J. Weaver and L. Carey (Research Associate CSU, Dept of Atmospheric Science) continue to work on data from the Fort Collins flood.   A 15-minute accumulating rainfall total, derived from the CSU-CHILL radar, is being matched to a log of E-911 calls.  This comparison will be part of an article on the flood being prepared for Weatherwise Magazine.

Evaluation has begun on an empirical method for predicting the 24-hour intensity of tropical storms and hurricanes.  This is a new version of the technique which was initially developed in 1992 by R. Zehr and R. Phillips.  It combines qualitative input based on animated GOES imagery with quantitative information on vertical wind shear and sea surface temperature from operational models.  It is being run routinely each day for Eastern Pacific and Atlantic tropical cyclones with the assistance of T. Kimberlain, Colorado State University graduate student.

Continued cooperative work with Dr. Gray's project includes participation in project meetings, data management consultations,  real-time tropical weather discussions, and class lectures.
