Are there tornadoes in Hawaii

DOUGLAS says "Aloha" in Hawaii, HANNA says "Hola" on the Gulf Coast

Three tropical cyclones are currently raging over the western Atlantic and eastern Pacific. Ex-tropical storm GONZALO - meanwhile degraded to a tropical low - is the weakest in the group. He moves north of the coast of Venezuela westwards and "dies" - to put it casually - to himself. At most it is enough for a "tired" gust of wind and a strong shower from above, but that's about it. The inhabitants of the affected islands such as Trinidad and Tobago are certainly used to different things.

Another caliber is ex-hurricane HANNA, which landed on the southern Texas Gulf coast as a category 1 hurricane on the Saffir-Simpson scale on Sunday night. This morning the cyclone is on the border with Mexico and is up to mischief there and in northeastern Mexico, but "only" as a tropical storm. While it was able to show mean winds of 115 km / h and significantly higher gusts this morning, today at noon it will "only" storm with about 85 km / h mean wind or with gusts of up to 100 km / h. However, there was not only wind in "flat" form, but also locally as a rotating version. Sporadic tornadoes developed last night on the southern Texas Gulf coast. HANNA can not only come up with a storm, but also with a lot of water. According to the National Hurricane Center (NHC), 150 to 300 l / m² in places in South Texas and Northeast Mexico, locally even up to 450 l / m² up to and including Monday. HANNA will weaken to the tropical low over Mexico during the course of the day. In the course of Monday, the storm should finally be history.

The last link in this "chain of three" is Hurricane DOUGLAS, which - on Friday for a short time still Category 4 - as Category 1 hurricane spilled over from east-southeast to Hawaii this afternoon. Today it is moving at around 26 km / h, initially just north of the Big Island and with its core grazes the islands of Maui, Molokai, Oahu and Kauai until Monday evening, slowly weakening. Medium winds of around 120 km / h and gusts of up to 150 km / h are likely to cause some damage, as well as the expected heavy rains. The Central Pacific Hurricane Center (CPHC) anticipates quantities between 150 and 250 l / m² - especially in the congestion in the mountains there. In the night of Tuesday he will finally withdraw west-northwest.

But that's not all: in combination with the wind direction and tides, parts of the coastal regions affected by DOUGLAS, but also by HANNA, could also be hit by a one to two meter high storm surge in addition to the heavy rain.

One can only hope that the damage will be kept within limits and, if at all, only in the material area.
