|Some information appearing in this report may be provided by or gathered from sources outside of the NWS. An effort is made to use the best available information but because of time and resource constraints, information from these sources may be unverified by the NWS. Accordingly, the NWS does not guarantee the accuracy or validity of the information. Further, when information appearing in this report originated from a source outside the NWS (frequently credit is provided) users requiring additional information should contact that source directly. In most cases, NWS employees will not have the knowledge to respond to such requests. In cases of legal proceedings federal regulations generally prohibit NWS employees from appearing as witnesses in litigation not involving the United States.
