• Stay on top of the latest conditions while away from shore with Iridium GO! connectivity.
WXHEADSUP™
We check your position, course, and speed for weather conditions in your vicinity and that you may encounter ahead. Results are reported back to you in seconds… way faster than downloading a bunch of GRiBs.
in order to get the same information that Weathermuffin provides you in seconds, you would have to download and interpret at least 10 different GRiB layers. How long would that take you?
Weathermuffin’s WxHeadsUp alerts actively monitor these conditions for you:
• Wave Steepness
• Confused Seas
• Wind Opposing Current
• High Current
• Satellite Infrared
• Lightning
• Gustiness
• Calm Winds
• Sustained Wind Speed
• Significant Wave Height
• Precipitation
• Visibility
CYCLONES
With timely data from leading government agencies, be on the lookout for hurricanes, typhoons, and other active and developing tropical cyclones.
Available storm data includes:
• Storm name and classification
• Present and future storm track (position over time)
• Maximum wind, gusts, and seas
• Storm speed and direction of travel
• 34-knot wind radius, 12 foot (3.5 meter) seas radius
• Closest point of approach (CPA) and time to CPA
• 48-hour and 7-day probability of cyclone development
• Time that track and forecast were issued
Plus, cyclones are optimized for quick download over Iridium GO!
SYNOPTIC CHARTS
Weathermuffin’s synoptic charts are produced by expert, professional meteorologists at NOAA. As a result, they depict information you won’t find in GRiB files, like the locations of fronts and the ITCZ.
Weathermuffin offers the following synoptic charts (analyses and forecasts):
• Surface
• Wave Height/Direction
• Wave Period/Direction
• Wind/Wave
• 500 MB
• Sea Surface Temperature
• Cyclone
(Some features require a paid subscription.)
Iridium GO! connectivity requires separate hardware and an active data subscription from Iridium.
