J. Weaver and L. Carey (CSU Research Associate, Department of Atmospheric Science) completed their work on  the Fort Collins flood, including a 15-minute accumulating rainfall total, derived from the CSU-CHILL radar.  Both the accumulations and the E-911 graphs have been added to Weaver's web presentation on the flood.  The new material can be accessed at: http://www.cira.colostate.edu.   Choose "Flash Flood" from the menu, choose Weaver presentation, then go to "Late Evening Rain" for the accumulations loops, or "Runoff and Rain Totals" for the E-911 graphs.

An empirical method for predicting the 24-hour intensity of tropical storms and hurricanes, is being run in real time for evaluation with 1999 Atlantic and Eastern Pacific cases.  This is a new version of the technique which  combines qualitative input based on animated GOES imagery with quantitative information on vertical wind shear and sea surface temperature from operational models. This work is supervised by Ray Zehr, and is being done by Todd Kimberlain and Eric Blake, Colorado State University graduate students.

As in past years during the "hurricane season" daily briefings are presented in the CIRA Lab with participation by CSU faculty and graduate students.  Briefings were presented by CIRA personnel and CSU graduate students.  A short article regarding the briefings was submitted for the CIRA Newsletter.

L. Grasso continued to collaborate with doctoral students on the numerical simulations of convective storms.
