The Guam forecast office issues a lightning &#8216;advisory&#8217; if lightning is possible or occurring within 20 mi of the Guam Airport, and a lightning &#8216;warning&#8217; if lightning is possible\/occurring within 5 mi of the airport. LightningCast probabilities will help in this task.  Forecasters will be evaluating its performance in the coming weeks.<\/p>\n\n\n\n<p>LightningCast imagery is available in a RealEarth instance <a href=\"https:\/\/cimss.ssec.wisc.edu\/severe_conv\/pltg.html\">here<\/a> (at that website, there is a small drop-down menu titled &#8216;Select Sector&#8217;;  Choose Guam).  An example animation is shown above.  (Guam is located at the outer fringes of Typhoon Nanmadol in the image) In contrast to the scenes under GOES-East&#8217;s and GOES-West&#8217;s view, GLM data are not available.  In the forecast office, ground-based lightning sources are available.  <a href=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2022\/09\/LightningCast_Lightning_Guam_20220913.mp4\">This animation<\/a> (from John Cintineo, CIMSS)  shows LightningCast probabilities with Earth Networks Total Lightning.  Animations online, as shown above, show only Himawari-8 data and LightningCast probability contours.<\/p>\n\n\n\n<p>As with GOES-R LightningCast computations, Himawari-8 uses Visible (0.64 \u00b5m), near-infrared (1.61 \u00b5m) and infrared (10.41 \u00b5m and 12.3 \u00b5m) observations.  Resolution differences at 1.61 \u00b5m (1 km for GOES-R and 2 km for Himawari-8) and slight differences in infrared spectral responses, especially for band 13 (centered near 10.33 \u00b5m for GOES-R and 10.41 \u00b5m for Himawari-8) may have an as-yet unknown impact on LightningCast probabilities.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At the request of the National Weather Service forecast office in Guam (where the National Weather Service&#8217;s day begins), CIMSS is computing a small region of LightningCast Probabilities that uses Himawari-8 data.
