Quietest Atlantic Hurricane Season Since 1986

By: Dr. Jeff Masters, 3:59 PM GMT on October 01, 2014

The traditional busiest month of the Atlantic hurricane season, September, is now over, and we are on the home stretch. Just three weeks remain of the peak danger portion of the season. September 2014 ended up with just two named storms forming--Dolly and Edouard. Since the active hurricane period we are in began in 1995, only one season has seen fewer named storms form in September--1997, with Category 3 Hurricane Erika being the only September storm. Between 1995 ...

QuikSCAT's Replacement, the RapidScat Ocean Wind Sensor, Installed on Space Station

By: Dr. Jeff Masters, 3:17 PM GMT on September 30, 2014

In November 2009, one of the greatest success stories in the history of satellite meteorology came to an end when the venerable QuikSCAT satellite failed. Launched in 1999, the QuikSCAT satellite became one of the most useful and controversial meteorological satellites ever to orbit the Earth. It carried a scatterometer--a radar instrument that can measure near-surface wind speed and direction over the ocean. Forecasters world-wide came to rely on QuikSCAT wind data...

Invest 97L Spinning Near Bermuda; Phanfone a Potential Threat to Japan

By: Dr. Jeff Masters, 2:27 PM GMT on September 29, 2014

An area of low pressure (Invest 97L) has formed just west of Bermuda, and is bringing heavy rain showers and gusty winds to the island. At 9:45 am AST Monday, the Bermuda Airport reported a waterspout. Winds have gusted as high as 39 mph on the island this morning, and 0.47" of rain had fallen between midnight at 11 am local time on Monday.

By: Dr. Jeff Masters, 3:18 PM GMT on September 27, 2014

(By Steve Gregory - Substituting for Dr. Masters who is on Vacation.)

Atlantic Basin Hostile to Tropical Cyclone Formation

The weak disturbance that was INVEST 96L is no longer of any significance as it became overwhelmed by both drier and stable air along with increased wind shear. What’s left of the disturbance has turned N/NE.

Although there are 3 other tropical Waves in the Atlantic basin – none pose any threat of devel...

Atlantic Disturbance 96L and Tropical Storm Rachel

By: Dr. Jeff Masters, 5:19 PM GMT on September 26, 2014

(By Steve Gregory - Substituting for Dr. Masters who is on Vacation.)

INVEST 96L NOT A THREAT

A small area of disturbed weather with periodic bursts of convection near 13°N/42°W remains disorganized as it continues to drift WNW at around 5Kts. Although wind shear remain moderate near 15Kts, there are indications of some outflow at high levels – the system remains surrounded by relatively dry and somewhat stable air which is inhibiting dev...
