Outreach Activities Crank Up to Start 2011

Winter Texan Expo
On January 11th and 12th, several of the NWS Brownsville team staffed a booth at the annual Winter Texas Expo at the McAllen Convention Center. An estimated three to five thousand seasonal and permanent residents attended the event, many asking questions about the local weather conditions, the expected conditions for the rest of winter and early spring, and office operations in general. Skywatcher Cloud charts (below), among other items, were quite popular! Thanks to Forecasters Joseph Tomaselli and Ryan Vipond, and to new Science and Operations Officer Doug Butts and Alfredo Vega for their participation!

Career Day
On January 14th, Senior Forecaster Greg Flatt and Forecaster Buddy Martin spoke to nearly two dozen high school students on careers in meteorology. The students who attended were treated to an interactive discussion on what it takes to become a meteorologist, followed by information on what the public, military, and private sector offers. Mr. Martin, who holds a Ph.D. in Atmospheric Science, helped explain the process in achieving an advanced degree.

Laguna Madre Trip
On January 20th, six member of the team (above right) went on a discovery mission up the Laguna Madre, hosted by Joseph Hilliard of the Texas General Land Office. The mission on a 27 foot vessel began in the Port Isabel Ship Channel, headed to the edge of the Brownsville Ship Channel and Boca Chica jetties, then ran north through the center channel of the Laguna Madre through Cameron, Willacy, and into Kenedy County to the "Land Cut", about one third the way into the county.

Laguna Madre Trip (Continued)
The mission allowed the staff to get a first hand look at the Laguna Madre waters for which daily forecasts and special warnings are issued; waters used by boaters and fishers year round, as well as the U.S. Coast Guard and even barge traffic, particularly between Port Isabel and Port Mansfield. Dozens, if not more than a hundred, small to medium sized fishing cabins (below) dot the edge of the channel, many which are vulnerable to a significant storm tide and very strong hurricane force winds. Such winds leveled many cabins in Kenedy County when Category 3 Bret slammed ashore; storm tides flooded or destroyed any existing cabins with Hurricane Allen (1980). Mr. Hilliard educated the crew on the local effects of wind on the chop and waves within the channel at various locations along the route. In Kenedy County, the crew saw up close the impact of a strong front, as smooth waters turned rapidly to a moderate chop (below, center).
