The Caribbean Sea

The National Hurricane Center is issuing advisories on Hurricane Iota, located inland over extreme northeastern Nicaragua.

Outside the influence of Hurricane Iota, isolated to scattered moderate convection is moving across the northern islands of the Lesser Antilles. Showers are also noted across the rest of the Lesser Antilles. Moderate to locally fresh trade winds are noted in the central and eastern Caribbean. Seas range 3-6 ft outside the influence of Iota.

A new area of low pressure could form in a couple of days over the central or southwestern Caribbean Sea. Environmental conditions are forecast to be conducive for some development, and a tropical depression could form by the end of the week while the system moves slowly westward or west-southwestward across the southwestern Caribbean Sea. Otherwise, moderate to locally fresh trades will prevail SE of the front in the NW Caribbean through the end of the week into the weekend. Conditions in the NW Caribbean will greatly improve this weekend as the front washes out.

The National Hurricane Center is issuing advisories on Hurricane Iota, located inland over extreme northeastern Nicaragua.

Hurricane Iota is centered near 13.7N 84.3W at 17/0900 UTC or 10 nm ENE of El Pia Nicaragua moving W at 8 kt. Estimated minimum central pressure is 950 mb. Maximum sustained wind speed is 90 kt with gusts to 110 kt. Iota is moving toward the west and this general motion is expected to continue during the next day or so. On the forecast track, Iota will move farther inland across northern Nicaragua today, and move across southern Honduras tonight and Wednesday. Additional rapid weakening is expected today into Wednesday, and Iota is forecast to dissipate over Central America by Wednesday night. Numerous moderate to strong convection is noted within 210 nm of the center of Iota. Scattered moderate and isolated strong convection is noted elsewhere within 360 nm in the N semicircle and 270 nm in the SW quadrant of Iota. Life-threatening flash flooding and river flooding is expected through Thursday across portions of Central America due to heavy rainfall from Iota. Flooding and mudslides across portions of Honduras, Nicaragua and Guatemala could be exacerbated by Hurricane Etas recent effects there, resulting in significant to potentially catastrophic impacts.

A new area of low pressure could form in a couple of days over the central or southwestern Caribbean Sea. Environmental conditions are forecast to be conducive for some development, and a tropical depression could form by the end of the week while the system moves slowly westward or west-southwestward across the southwestern Caribbean Sea.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

Accumulated rainfall in the hilly central and southern areas of Belize, extending northwards along the central coast will be in the order of 10-20 inches through Saturday 6:00 pm. Expect dangerous flash floods and flooding with this type of rainfall, now that soil moisture is at field capacity!.

Take heed and be prepared!

This HURRICANE IOTA crossed the Nicaragua coast last night as a Cat.4, dropping a it went in, but is still listed as Cat.1 this morning, half way across that country, where it will now start to reach hillier country, then rapidly reduce its winds.

The normal clouds over Belize are from the NNE but outer bands of active weather from the Hurricane are now beginning to come over Belize. There is a particularly strong ling presently off shore, going into Toledo first, but stretching right up to Corozal. There are patches of rain in that line, some heavy.

Presently the clouds are overcast, but there are patches through them in places. But there will be bands of rain coming in, starting in the south, then occurring further north, but with dry periods between them. I am not expecting any wind from the hurricane, but heavy rains can cause their own winds.

You can see the circulating waves coming round over Belize from the east and NE with patches. Several high cloud swellups the length of Belize. More moving in tomorrow. The actual storm is now down to Tropical Storm, probably dropping to just Depression over night, but the rain is likely to continue on and off through tomorrow, quite possibly even more rain than today. . . I expect there still to be some rain into Thursday. That accumulated rain is 6 - 8" generally and 10 - 12" in some places, such as the eastern mountains. So far today, I have got 41mm ( 1.6" )
