![]() *Areas with a high concentration of lightning activity may also be experiencing a high intensity of rainfall and caution should be taken when residing or driving in those areas. Zoom 3 – Harris County and surrounding areas.Zoom 2 – Bryan/College Station + Houston Metropolitan Area.Green boxes are HLMA sensor locations.īottom right box – North-south spatial and altitude extent of lightning activity. Middle right box – Frequency of lightning sources at a given height with the number of sources per 10 minutesīottom left box – Map view of lightning activity with counties overlain. Middle left box – East-west spatial and altitude extent of lightning activity Central Standard Time is 6 hours behind UTC time from the first Sunday in November through the first Sunday in March.Central Daylight Time is 5 hours behind Universal Coordinated Time (UTC) from the first Sunday in March through the first Sunday in November. Live lightning detector and track thunderstorms as they form over the UK and Europe, including live animation of UK lightning strikes.Top box – Time series of the altitude and density of lightning activity within the past 10 minutes. Listen to local media outlets (radio, TV, internet, NOAA weather radio) in any event of inclement weather.Adjust any outdoor plans if lightning activity is ongoing in your area.Seek shelter if lightning is observed or thunder is heard.When lightning is detected in your area, please adhere to all lightning safety guidelines presented by the National Weather Service. The HLMA can advise when lightning activity may occur in a particular area. The data should never be used as a means for lightning protection. Publicly available HLMA data are posted every minute. Lightning data can be requested by contacting Dr. The link to the HLMA website is available here. ![]() Hence, deep convective clouds that develop over the Gulf of Mexico can be examined by the magnitude of lightning activity. Using lightning to illustrate the rapid intensification (RI) and rapid weakening (RW) of tropical cyclones presents the opportunity for the HLMA network to examine the total lightning structure within tropical cyclones that impact the Texas coast. The primary research goals of the network are to (a) investigate the charge structure of total lightning within thunderstorms as they develop, (b) examine the relationship between electrical activity within deep and shallow convection from continental and tropical systems with respect to precipitation rates, and (c) examine any potential impacts of lightning on urban, coastal, and marine environment and infrastructure. The VHF source data are grouped into 80 and 400 μs bins which are used for scientific analysis and real-time data web image display. The sensors utilize a time-of-arrival calculation method which provides 3D lightning information around the Houston Metropolitan area and 2D information to surrounding regions within a 250 km radius of the HLMA network center (which includes the Gulf of Mexico). ![]() It is a surface-based network of twelve sensors which monitor VHF radiation source events from lightning on a locally unused TV channel (e.g., Ch. The Houston Lightning Mapping Array (HLMA) network was established in April 2012.
