The potential for greater evaporation and higher rain rates is true in general for all types of storms, on land or sea.
That basic physical understanding, confirmed in computer simulations of these storms in current and future climates, as well as recent events, leads to high confidence that rainfall rates in hurricanes increase by at least 7% per degree of warming.
Storm strength and rapid intensification
Scientists also have high confidence that wind speeds will increase in a warming climate and that the proportion of storms that intensify into powerful Category 4 or 5 storms will increase. Similar to rainfall rates, increases in intensity are based on the physics of extreme rainfall events.
Damage is exponentially related to wind speed, so more intense storms can have a bigger impact on lives and economies. The damage potential from a Category 4 storm with 150 mph winds, like Ian at landfall, is roughly 256 times that of a category 1 storm with 75 mph winds.
(CNN) Tropical Storm Julia is now categorized as a hurricane with maximum sustained winds of 75 mph, according to the National Hurricane Center on Saturday.
The storm is passing between San Andres and the Providencia islands and is moving west at 17 mph, the NHC said in a 7 p.m. ET update.
Hurricane Julia is expected to strengthen slightly before striking the Nicaraguan coast early Sunday, according to the NHC.
Along with hurricane-force winds, life-threatening rainfall of 6 to 10 inches, with isolated amounts of up to 15 inches, is possible in Nicaragua.
GUATEMALA CITY (AP) — Former Hurricane Julia has dissipated, but is still drenching Guatemala and El Salvador with torrential rains Monday after it reemerged in the Pacific following a pounding of Nicaragua.
At least 19 people were reported dead as a direct or indirect result of the storm.
Guatemala’s disaster prevention agency said five people died after a hillside collapsed on their house in Alta Verapaz province, burying them.
Authorities in El Salvador said five Salvadoran army soldiers died after a wall collapsed at a house where they sought refuge in the town of Comasagua, where hundreds of police and soldiers have been conducting anti-gang raids. Another soldier was injured.

Less than 2 percent of the users who participated in this virtual mobilization were in Cuba. Most of those who made the call to “fire up” the streets in Cuba were connected to American technology platforms and did so while hundreds of kilometers away from the country that remained in darkness. Perhaps some on the island kept their battery-powered radio. Still, what millions of Cubans had in the palm of their hands was not a bottle of Hemingway’s rum but a cellphone connected to the internet (the country of 11 million inhabitants has 7.5 million people with access to social media).
… Imagine this panorama: you are anguished with the here and now. You have no electricity and no drinking water. What little food you have bought with great difficulty and kept refrigerated will go bad in no time. You don’t know what has happened to your family that lives in the western provinces, where the damage is apocalyptic. You have no idea how long this new crisis will last. Daily life before the hurricane was already desperate due to the economic blockade imposed by the United States, inflation, and shortages being faced by Cubans. Still, you see on your mobile that “everyone” (on the internet, of course) seems to be doing well and has plenty, while thousands of people on social media (and their trolls) shout that the culprit of your misfortune is the communist government. Your only light source is the mobile screen, which works like Plato’s allegory of the cave: you sit with your back to a flaming fire while virtual figures pass between you and the bonfire. You only see the movements of their shadows projected on the walls of the cave, and those shadows whisper the solution to your desperate reality: #CubaPaLaCalle.
MEXICO CITY (AP) — Tropical Storm Karl moved slowly toward Mexico’s southern Gulf coast on Friday, and while it was not expected to grow into a hurricane, forecasters warned of the danger of flash floods from heavy rains in the region.
The storm was expected to make landfall in Veracruz state or Tabasco state by late Friday or early Saturday.
Karl had maximum sustained winds of 45 mph (75 kph) on Friday morning, the U.S. National Hurricane Center said. The storm was centered about 80 miles (130 kilometers) northwest of Ciudad del Carmen and headed south-southeast at 7 mph (11 kph).
A tropical storm warning was in effect from Coatzacoalcos to Sabancuy.
