ANNOUNCEMENTS - Week 3

28 September 2001

  1. Congratulations! The compiling of registration data from LIT leaders (a few are still to be heard from!) indicates we have about 190 participants in 31 LITs operating with participants in 25 states. We are grateful to all of you LIT leaders and other LIT members for this great effort.

  2. Preliminary reports from LITs indicate the overall operation of DataStreme has been going well. We appreciate those "Reports from the Field" that have been sent to Ed Hopkins. We would like to see more, especially from LITs and participants in weather-impacted areas. They add the human interest to weather.

  3. Materials for the second meeting (weather radios, books, temperature strips) are being shipped to LIT leaders as registration materials arrive. Your quantities are based on the forms we have received. If the box has not arrived by Thursday, 4 October, contact us so we can track its location.

  4. Mentors should remind their mentees of the upcoming mid-course meeting. Everyone (participants and LIT members) should bring their Pressure Blocks (for Activity 5B) to the mid-course meeting.

  5. LIT leaders are reminded that you need to use both the DataStreme Expense Reimbursement and Program Group Meeting Forms from the back of the LIT Manual and attach receipts to it for reimbursement of meals from meetings.

  6. Reminder:
    Effective immediately, all future mailings and correspondence should be directed to:

    American Meteorological Society
    Education Program
    1120 G. St., N.W., Suite 800
    Washington, DC 20005

  7. The AMS Washington office will be moving to its new location starting Friday, Oct. 5 and extending through the weekend. We expect that course delivery will not be interrupted. However, our telephone and email services may not be operating on Friday, Oct. 5.
