MINUTES of the CLEWX SKYWARN STEERING COMMITTEE MEETING July 14, 1990 The meeting was called to order by Chairman Dave Prestel, W8AJR, at 10:05 am. Those in attendance were: Marvin Miller, NWS Dick Bomboy, WA3USH Rick Silverio, WB3JDI Jack Davis, N8DAI Scott Yonally, KC8SS Bill Parks, K8JZN Bill Hess, K8SGX Chris Mize, WD8OCS Marv Grossman, W8AZO Tex Crider, N8FPH George Henzler, WB8HHZ Dave Prestel, W8AJR Dave Kersten, N8AUH Bill Craig, Dir. EMA Trumbull Co. W8AJR said all areas represented by this Steering Committee have successfully tied in with Cleveland NWS (CleNWS), since our last meeting (4/21/90), except Northwest Ohio. Brief reports were solicited from each: + KC8SS said Mansfield doing fine in-so-far as reaching CleNWS via 2M. They've been busy with severe weather, receiving more than their share so far in 1990. + N8DAI said Trumbull County doing okay, at this time. + WB3JDI reported Pennsylvania making CleNWS okay via 2M and Packet on .05 Rick said they have the weather available on phone BBS, and they pick up reports there, and enter them on the Packet system, which is reported to be very good thru Western Pennsylvania. + WB3USH said Erie radar was giving them problems in early July with reports of storm severity that were not consistent with CleNWS, Erie showing greater intensities than CleNWS. The problem was dumped onto the Amateur community, but is the NWS's to resolve. Dick will be meeting with Marvin after this meeting to further discuss. + WD8OCS said they have been having some trouble getting traffic into & from CleNWS, probably because of new operators at CleNWS. This situation will resolve itself with experience on the part of the hams at CleNWS. + WB8HHZ said Toledo has successfully relayed information to & from CleNWS via WD8CHL, Jim in Berlin Heights, thru the 147.15 repeater. + N8FPH said Toledo area Skywarn (WD8C and N8FPH) can be reached at W8HHF Packet, and that the NWS at Toledo Airport is on Packet at W8MTU-1. Marvin Miller reported there has been 180 Events (Tornado & Severe Thunderstorms) statewide this year. He is pleased to see the group working on the new communications network to have it in place and functioning well ahead of NEXRAD. Marvin explained radar looks at the size of the raindrops in a storm - the larger the drop, the heavier the rainfall. At least four different radar sites watching the night of the Shadyside flooding did not indicate the type of rainfall that was actually occurring: Tropical, small droplet size but very great density. Several of these stations had "10 centimeter" radar, the most sensitive for CLEWXSKYWARN (Con't) July 14, 1990 p. 2 this type of surveillance, but none reported the severe rainfall that resulted. Marvin pointed out Doppler is also the 10cm type radar, so he doubts it would have done any better at alerting NWS personnel to the hazard. He went on to point out NWS needs well trained spotters to advise them of the actual conditions seen and help avoid this type of anomaly. KC8SS asked about obtaining more advanced Tornado WARNINGS, and Marvin explained, by definition, a warning isn't issued until there has been an actual sighting of a funnel. N8FPH asked about the reliability and capability of Doppler radar as it looks as if Toledo will not be gaining anything with this transition, may in fact lose the advantages they now have. Marvin said the optimum range of Doppler is about 80 miles. It can see further and interpret what it sees. In updrafts (etc.) it creates a VIL number (Vertically Integrated Liquid) which indicates how severe the weather in that storm cell may be: The higher the VIL number, the worse the storm. The VIL number at distance shows up some 10 minutes before the event manifests itself on the ground. Toledo will be on the fringes of several Doppler radar sites; Pontiac, Mich.; Peru, Ind.; and Cleveland, Ohio. Marvin again emphasized the need for SKYWARN reporters will NOT diminish with Doppler, but will likely become more of a necessity as NWS local manning is reduced (including radar sites). W8AZO brought forth some comments on the Shadyside flooding and the communications problems there. Throughout that area, most everything is built in the valleys (gullies). When heavy rains come, they wash down the slopes of the hills and fill the gullies. Typically, there is a main road in the gully, with homes built on both sides of the road, and bridges crossing the gully. The rain came down with such intensity that it washed all kinds of debris (small sheds, automobiles, busses, etc.) into the gully streams, and these built up at the bridges, which gave way after the pressure on them became too great, which then unleashed the lakes that had built up behind them to wash away everything below. The resultant flood washed away utility poles (telephone, power, etc) and there was no way to communicate with the area. The National Guard was activated (112th Engineers Group from Cleveland area) and they did not have adequate communications for the type of terrain. Finally, cellular telephone, working through a system across the river provided the first reliable communications. That Amateur radio wasn't called upon was apparently an oversight or miscommunication on the part of someone. W8AJR spoke about the 6-Meter backbone system, proposed for the upper echelon of the SKYWARN network, explaining that the main transmitter is in Novelty, Ohio, with remote inputs at: Mansfield, Wooster, Thompson, Amherst & Geauga County, with additional sites under consideration. There is also access to the Michigan 6-meter network. This backbone would allow NWS operators to communicate with more distant areas, than they have been able to do in the past. This network will require both 6M & 2M capability, with tone alerting. Tone alerting will allow the NWS to advise the local Skywarn areas of impending severe weather, as well as giving the local nets the capability of alerting CleNWS of CLEWXSKYWARN (Con't) July 14, 1990 p. 3 severe weather reported by local spotters. Also, CleNWS will have the ability to monitor various local Skywarn nets for reports, as needed, to keep in touch with the local situation. A second frequency on 2M for each net will be a necessity, for local simplex liaison. The estimated cost for each operating site is $300.00, using surplus gear (assuming availability) and some donations. WB3JDI & WD8OCS have 6M accessibility at this time, Trumbull County will have this capability soon. Other local frequencies and bands may be used, but each area MUST maintain communication capability between 6M & 2M for local alerting from CleNWS, and to allow CleNWS monitoring capability. WD8OCS & others to the west are working on UHF linking via a net covering Lorain County & west. When placed into operation, this net will provide excellent coverage to the west & some to the south. W8AJR reported a 2.5KVA emergency generator has been secured for the 6M transmitter site to assure reliability in the event of power disruption. The generator will be procured with Lake Erie Amateur Radio Association funds, with the understanding that this group, CLEWXSKYWARN, would purchase back through other available funding (discussed later). At this time there is concern from the owners of the site about gasoline being stored there: Resolution on this matter will be sought. WD8OCS reported little actual progress in the quest to use several old AT&T relay towers for sites for remote inputs for the 6M network. Chris feels the idea will be more likely to succeed if a properly planned proposal, thoroughly explained & documented in writing, can be presented at the time of the request. W8AJR inquired as to whether any members of the body had ever sought grants from business groups, or others. Both Erie & Toledo have. Dave said a LEARA member has offered to assist in seeking grants or other funding using his experience and position (executive with Austin Company) to make contacts, prepare & mail letters, etc. We would need to clearly explain our purpose, need, estimated costs, etc. to solicit participation. Dick (USH) suggested we may need to use formal grant applications, either Federal or State format. Rick (JDI) said money may be available from County EMA, or others. Bill Craig explained briefly (from the perspective of a local EMA Director) how funding may be obtained through the EMA. He explained EMA funding is available only to a RACES group, but he doesn't believe there is any reason funding could not be used to establish the local base of operations for Skywarn operations. WB8HHZ said Lucas County is very active with ARES/RACES, and through their local EMA they had recently completely renovated an operations center in the basement of the County Jail, complete with new amateur CLEWXSKYWARN (Con't) July 14, 1990 p. 4 radio equipment, antenna systems, etc. W8AJR requested all to contact their local EMA Director to see if funding may be available. Equipment must remain at the County Emergency Operations Center, according to Bill Craig, but this should not present any serious problems in most cases. Bill mentioned EMA Directors are now preparing their requests: The requests must be submitted by July 20th, so time is very short to seek involvement. Dave asked all who would be obtaining funding from their EMA to advise him as quickly as possible to help those seeking other outside funding have accurate figures of costs expected. Bill Craig also mentioned the State will fund about $600.00 for computer equipment to use at the EOC for a Packet station, and they will also probably provide an additional several hundred dollars toward the other required equipment (TNC, radio, etc). W8AJR commented on Packet radio weather information. Dave explained the packet station at CleNWS is provided with hourly updates, and these are downloaded when there is significant change from the previous report (forecast). Special Alerts and Warnings are downloaded immediately upon receipt, and are forwarded to those packet stations desiring this information. A problem was recently encountered when a local PBBS operator took WXNET messages and forwarded them automatically to other boards. The forwarding was not the apparent complaint, rather that the information was being received in Toledo a day late, and they were not interested in Cleveland weather! Dave said the software will be modified to provide weather information to those PBBSs' who desire this information, with it customized to provide only the information they want for their area of coverage. Much more than Cleveland information is readily available, and can be downloaded if requested. WB3JDI presented a map they will be starting to use for Crawford Co., Pennsylvania Skywarn very shortly. This map is marked off in Grid Squares based on the ARRL Grid Locator Map. A general discussion ensued, and it is felt we should prepare something similar for at least our area of coverage, and possibly the entire state, based on the work demonstrated by Rick (JDI) & Dick (USH). The next meeting will be September 29th @ 10:00 am in the Cleveland NWS Conference room. The meeting adjourned at 12:05 pm. Respectfully submitted, Dave Kersten - N8AUH @ NO8M
