Tropical Storm Bertha Racing Northeast Between the U.S. East Coast and Bermuda (FORECAST)

August 6, 2014

Tropical Storm Bertha Highlights

- Bertha is accelerating northeast off the Northeast Coast.

- High surf, rip current risk for parts of East Coast.

- Should be a post-tropical cyclone in 24 hours or less.

Bertha, the second hurricane of the 2014 Atlantic hurricane season, was downgraded to a tropical storm during the early morning hours on August 5 between North Carolina's Outer Banks and Bermuda.

As you can see in the satellite image below, Bertha's appearance has become ragged, with an exposed low-level circulation center (yet again) with occasional thunderstorms flaring on the circulation's periphery.

Bertha is experiencing increasing wind shear as it accelerates to the northeast, thanks to meeting the upper-level westerlies, such that its evolution to a post-tropical cyclone is imminent by late Wednesday or early Thursday.  

The post-tropical remnant of Bertha may brush southeast Newfoundland on Thursday, but will be much weaker than that of Arthur in early July.

There are no watches or warnings for land, but tropical storm warnings are in effect over water for marine interests well off the East Coast of the U.S.

Swells of 3 to 5 feet generated from Bertha may reach the coast from eastern North Carolina into southern New England, with an enhanced threat of rip currents as well. This threat for elevated surf and rip currents will subside from south to north by late Wednesday. 

Keep in mind the rip current hazard is often highest when wave heights are only moderate, as fewer people may recognize the risk, particularly on an otherwise fair-weather day.

Current Infrared Satellite

This infrared satellite image shows how cold (and therefore how high) the cloud tops are. Brighter orange and red shadings concentrated near the center of circulation signify a healthy tropical cyclone.

Current Visible Satellite (Daylight Hours Only)

This visible satellite image shows the clouds as they would look to the naked eye from outer space. As a result, the image will not show any clouds when it is nighttime over the depicted area.

Storm History

Bertha formed late Thursday night, about 275 miles east-southeast of Barbados. It moved across the Lesser Antilles, causing minimal damage.

Bertha produced over 10 inches of rain in some areas of Puerto Rico. Bertha's rain should eventually prove beneficial with regards to the drought in Puerto Rico. Bertha later moved over the Turks and Caicos Islands with little fanfare.

Invest 94L Off the Coast of Africa May Slowly Develop

July 29, 2015

The first African tropical wave worthy of being classified by NHC as an area of interest (an "Invest") has emerged from the coast of Africa, and lies a few hundred miles southeast of the Cape Verde Islands. Invest 94L has conditions that favor some slow development over the next few days.

Another Dry California Precipitation Season Draws to a Close

The 2014-2015 precipitation season ended today (June 30th) and the drought continues unabated. Although the precipitation totals for the July 1-June 30 (2014-2015) period do not appear to be all that bad (generally 60-85% of average) this does not tell the whole story. A very wet December saved what otherwise would have been a catastrophically dry year. In fact, the past six months (since January 1st) have been one of the driest such periods on record for many locations, including San Francisco. Here are some details about the past rainy season and the current drought.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
