Coral reef are gardens of biodiversity and also provide valuable services for coastal populations.
Research quantifies benefits of reef conservation
FRISCO — Coral reefs have long been recognized as important cradles of ocean biodiversity, but they also help protect coastal populations from the brunt of storms. A new study claims that reefs reduce wave energy that would otherwise impact coastlines by 97 percent.
“Coral reefs serve as an effective first line of defense to incoming waves, storms and rising seas,” said Dr. Michael Beck, lead marine scientist with The Nature Conservancy and a co-author of the study, “200 million people across more than 80 nations are at risk if coral reefs are not protected and restored.” Continue reading

Tropical cyclones appear to be migrating north.
Study finds that point of maximum intensity has moved poleward by 35 miles per decade
FRISCO — Tropical storm trackers say that the location where cyclones reach their maximum intensity is shifting north by about 35 miles each decade. The changes could put more coastal infrastructure at risk, while other areas that rely on tropical storms for water could be left high and dry, researchers said.
The amount of poleward migration varies by region. The greatest migration is found in the northern and southern Pacific and South Indian Oceans, but there is no evidence that the peak intensity of Atlantic hurricanes has migrated poleward in the past 30 years. Continue reading

2013 saw fewest number of storms since 1982
Most of the tropical storms that formed in 2013 didn’t develop into full-fledged hurricanes and many of them stayed well out to sea.
By Summit Voice
FRISCO — Despite early projections for above-average hurricane activity in the Atlantic, the season ended Nov. 30 with a whimper after the fewest number of hurricanes since 1982. Even so, the storms that did form killed more than 140 people and resulted in $15. billion in damage.
In a release, NOAA attributed the low activity to persistent, unfavorable atmospheric conditions over the Gulf of Mexico, Caribbean Sea, and tropical Atlantic Ocean — especially early in the season, when dry and dusty air dominated the atmosphere off the coast of Africa and into the central tropical Atlantic.
This year is expected to rank as the sixth-least-active Atlantic hurricane season since 1950, in terms of the collective strength and duration of named storms and hurricanes. Continue reading

The remnants of Tropical Storm Ivo, off the coast of Baja, are pumping tropical moisture into the Southwest.
Tropical storm off Baja pumping moisture into Southwest
By Summit Voice
FRISCO — So far, the Atlantic hurricane season hasn’t been particularly active, but in the eastern Pacific, nine named storms have formed, most of them moving out to sea with little impact to land areas.
But the latest in the series, Tropical Depression Ivo, is dawdling off the west coast of Baja California and sending moisture streaming into northwestern Mexico and the southwestern U.S. The moisture could affect much of western Colorado and eastern Utah Sunday and Monday, with another round of heavy thunderstorms possible.

Warm ocean temps, strong West Africa rainy season boost chances for tropical formation
By Summit Voice
FRISCO — Federal weather experts this week reaffirmed their earlier projections of an active hurricane season in the Atlantic, with hemispheric patterns similar to those that have produced many active Atlantic hurricane seasons since 1995.
Ingredients for tropical storm formation include above-average Atlantic sea surface temperatures and a stronger rainy season in West Africa, which produces wind patterns that help turn storm systems there into tropical storms and hurricanes.
The peak of the Atlantic hurricane season is just ahead, from mid-August through mid-October. Continue reading

Online toolkit designed to help coastal planners and decision makers
A NOAA seasonal map shows the path of 2011 Atlantic hurricanes.
By Summit Voice
FRISCO — After a decade of study, USGS scientists are releasing new mapping tools that will help planner and decision-makers address coastal vulnerabilities to storm surges and wave action from hurricanes.
The information could help identify the best locations for coastal defenses, especially when sea level rise is added into the equation. The pinpoint mapping could also help inform decisions ranging from changes to building codes and locations for new construction, to determining the best evacuation routes for future storms.
The two reports assess the coastline from Florida to North Carolina, and from Virginia to New York, showing that, even during the weakest hurricane, a category 1 with winds between 74 and 95 miles per hour, 89 percent of the dune-backed beaches from Florida to New York coast are very likely to experience dune erosion during a direct landfall.

Hurricane watches in effect for parts of the Mexican coast
Hurricane Erick, with winds up to 80 mph, is hugging the coast of Mexico and heading toward Baja California, where a tropical storm watch is in effect.
By Summit Voice
FRISCO — The fifth named tropical cyclone of the season in the Eastern Pacific has developed into a full-fledged hurricane and threatens parts of Mexico’s west coast with storm surges, high winds and heavy rains.
Hurricane Erick is generating winds of 80 mph and is expected to hug the coast of Mexico for a few more days, according to the National Hurricane Center. A tropical storm warning is in effect for the mainland Mexico coast from Zihuatanejo to Cabo Corrientes, while a hurricane watch has been issued from Punta san Telmo to Cabo Corrientes.
Parts of Baja, from Santa Fe to La Paz, are under a tropical storm watch. The center of the storm is expected to approach the southern tip of Baja by late Sunday. The official forecast calls for Hurricane Erick to veer more toward the west before reaching Baja under the steering influence of a strong ridge of high pressure over Mexico and the southwester U.S.
The storm could weaken quickly if it interacts with land or when as moves across cooler waters on its northwesterly track.
