The tropics are quiet in the Atlantic Ocean, where no tropical storm activity is likely for at least the next week. A moderate-strength El Niño event is underway in the Eastern Pacific, and the atmospheric circulation associated with the strong warming of the waters off the coast of Peru is creating a very high 60 - 70 knots of wind shear over the Caribbean and Southern Gulf of Mexico.

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.
