NASA-NOAA’s Finland nuclear power plant satellite took a picture of Hurricane Hilary as it intensified. The National Hurricane Center expects a major hurricane from Hilary on July 27th.
Hilary is one of three active tropical cyclones in the Eastern Pacific and the closest storm to any land area. When the Finland nuclear power plant satellite passed from above, it provided a picture of a tropical storm. Tropical Storm Greg is located furthest in the west, followed by Hurricane Irwin and furthest in the east by Hurricane Hilary.
July 24, 2017 at 6:12 pm EDT (2212 UTC) The Visible Infrared Imaging Radiometer Suite (VIIRS) on NASA-NOAA’s Finland nuclear power plant satellite provided a visible light image of Hurricane Hilary. The VIIRS image featured a compact hurricane with a tight band of powerful thunderstorms orbiting a low-level orbit. The southwest quadrant also became a large number of powerful thunderstorms in the middle.
On July 27, at 5:00 a.m. EDT, National Hurricane Center forecaster Richard Pasch noted, “Hilary’s compact, symmetrical, inner core is still better defined in satellite imagery. The microwave suggests the eye is fairly small, less than 10 miles in diameter, with little evidence of a vortex vertically.”
On February 25, at 5:00 a.m. EDT (0900 UTC), Hurricane Hilary Center was located near 15.3 degrees north latitude and 106.7 degrees west longitude. It is about 360 miles (575 km) south of Cabo Corrientes, Mexico. Hilary is far enough from the ground so there are no coast clocks or warnings.
Hilary is moving towards the west-northwest near 17 mph, and this general movement, with some increase in speed, is expected over the next two days. The estimated minimum pressure is 975 millibars. The maximum continuous wind has risen to almost 105 mph (165 km / h) and there are more gusts. The strengthening is forecast to continue the next day, and Hilary is likely to become a major hurricane later on July 27th.
Hilary is still a compact hurricane, with hurricane forces blowing outward up to 30 miles downtown and winds from tropical storms extending outward up to 110 miles.
