![]() ![]() ( A record 30 named storms formed in 2020. There were 14 named storms last year, after two extremely busy Atlantic hurricane seasons in which forecasters ran out of names and had to resort to backup lists. 10, NOAA officials revised their estimate upward, to 14 to 21 storms. In late May, the National Oceanic and Atmospheric Administration predicted that there would be 12 to 17 named storms this year, a “near-normal” amount.

After a review of an unnamed January storm, Hurricane Center officials said it also would have qualified for a name. Additionally, simulated radar is derived from numerical models, and the output may differ from human-derived forecasts. Tammy is the 19th named storm to form in the Atlantic in 2023. A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity. Tropical-storm-force winds, with sustained speeds of at least 39 miles per hour, typically arrive as weather conditions begin to deteriorate, and experts say their estimated arrival time is a good deadline for completing storm preparations and evacuating if asked to do so. The post-tropical cyclone had sustained wind speeds of 40 miles per hour. Tammy remained a post-tropical cyclone in the Sargasso Sea early Sunday Eastern time, the National Hurricane Center said in its latest advisory. If the radar animation of the last hours shows local thunderstorms or precipitation cells forming and disappearing in an irregular manner, then the forecast is not vey accurate.Less than a day after becoming a post-tropical cyclone, Tammy became a tropical storm again on Friday. The forecast works very well when weather fronts or large organized precipitation structures are moving regularly, without disappearing or being created. Real weather is more complex than just the displacement of existing precipitation cells. Longer forecasts are not possible, as new precipitation cells are developing or existing ones are disappearing within a short time. Historically Strong El Nio may be on the way, expert ocean. This so called precipitation nowcast is the most accurate precipitation forecast possible but the forecast horizon is limited to about an hour. Sea surface temperature anomaly off the west coast of South America on October 11, 2023. ![]() The rain/snow forecast is computed by estimating the movement of precipitation cells observed by radar and extrapolating this movement into the future. West Java: How accurate is the radar based forecast? Moreover, some countries do not operate a weather radar network, and in those countries satellite data is used to estimate rainfall, which is less accurate than a realtime weather radar. Note that lightning is not shown on the forecast, as it cannot be predicted. The interactive map makes it easy to navigate. EUMETSAT Meteosat images are updated every 15 minutes. See the latest United States RealVue weather satellite map, showing a realistic view of United States from space, as taken from weather satellites. ![]() Live satellite images are updated every 10 minutes from NOAA GOES and JMA Himawari geostationary satellites. Light blue indicates drizzle, blue a medium intensity, and red and yellow indicate very strong precipitation, usually associated with thunderstorms.Ĭurrent lightning strikes are marked with small orange dots on the map (Europe only).

The radar map is updated every 5 minutes with a new radar observation.
