There is a very large ITCZ activity in the central Caribbean, just south of Jamaica.
A long way from Belize, but we have to keep watch on things like this, this time of the year, storms can develop fast and just on our door step. The hurricane people do not have any storms or even areas of interest for any part of the Atlantic or Caribbean.

====================Monthly Weather Summary, September 2020
National Meteorological Service of Belize
September is typically a wet month for the country of Belize. It also coincides with the peak of the Atlantic Basin Hurricane Season and a significant amount of the historical tropical cyclones that have affected the country occurred during the month of September. Apart from tropical cyclones, other systems that typically affect Belize during the month of September include tropical waves, Tropical Upper Troposheric Troughs (TUTTs) and at times cold fronts and frontal shear lines affect the country as early as September.
The morning of September first 2020 saw the development of Tropical Storm Nana over the central Caribbean Sea, with maximum sustained winds of 50mph. Tropical Storm Nana was moving west at 18mph and was projected to make landfall on Belize, prompting a tropical storm watch for the entire coastline of the country. In the evening, the tropical storm watch was upgraded to a hurricane watch as the official forecast from the National Hurricane Center was for the system to become a hurricane before making landfall. However, mainly fair and warm weather prevailed over most areas on that day. At 9am on the second of September a hurricane warning was issued from Belize City to the southern border as the projection was for a category 1 hurricane to make landfall near southern Belize within 24 hours. Tropical Storm Nana had maximum sustained winds of 60 mph and continued to track westward at 17 mph. Isolated thunderstorms and showers started to affect northern districts in the afternoon then coastal areas by early evening. At 6pm Tropical Storm Nana was about 100 miles east-southeast of Belize City and at 9pm, was about 48 miles east of Dangriga Town and about 60 miles southeast of Belize City. At that time Nana was upgraded to a hurricane as maximum sustained winds had increased to near 75 mph. In Belize City, winds were gusting to near tropical storm force strength and the projected area for landfall was south of Dangriga, and near to Hopkins village in the Stann Creek District. Hurricane Nana made landfall around 11:45pm in this general area. Some reports suggest hurricane force winds occurred in the Hopkins area and a weather station at Carrie Bow Caye, reported sustained winds of 61mph with gust of up to 75 mph.
Hurricane Nana weakened to a tropical storm soon after landfall, with gusty winds impacting mostly inland areas and heavy rainfall mainly over the Toledo district. Later that morning of the 3rd the storm was further downgraded to a tropical depression over the southwest portion of the country. Winds had decreased but heavy rainfall continued to affect the Toledo district.
The approach of a tropical wave on the 4th led to an increase in moisture resulting in a few showers and thunderstorms around the country that continued on the 5th during the passage of the wave. Showers and thunderstorms increased on the night of the 5th through to the early morning of the 6th with the activity gradually decreasing during the day.
A slack pressure pattern dominated across the area from the 7th through to the 11th and conditions were relatively moist. Showers and thunderstorms were generally isolated during the period except for a few showers and thunderstorms that affected most areas during the night of the 9th.
The second tropical wave for the month crossed the country around midnight on the 12th and supported a few showers and isolated thunderstorms mostly over the Orange Walk district and over southern coastal areas with only isolated activity later that morning. Conditions continued relatively moist on the 13th supporting a few showers and isolated thunderstorms inland, north and south in the afternoon.
Moisture decreased over the area from the 14th to the 20th and a slack pressure gradient maintained light and variable winds. Warm and mostly fair weather prevailed from the 14th to the 17th with only isolated thunderstorms and isolated showers inland in the afternoons and over the Toledo district at nights. A warning for severe thunderstorms was issued after mid-morning on the 18th as strong thunderstorms affected most areas of the country except the Toledo district. This warning was discontinued by early evening as only isolated thunderstorms and isolated showers developed along the coast and over the south during the latter part of the evening. Conditions continued warm and mostly fair with only isolated activity on the 19th and 20th.
Generally fair conditions prevailed across the country from the 21st through to the 24th. Showers and thunderstorms were generally isolated with a few more along with isolated thunderstorms at nights over the Toledo district. A few showers and isolated thunderstorms occurred mostly over northern and coastal areas on the 25th as a low center dominated the country. The 26th to the 28th saw a return to mostly dry conditions during the daytime with only isolated thunderstorm activity over the mountains in the afternoon and over southern districts during the night time.
The last two days of the month were relatively moist as a pre-frontal trough over the Yucatan Peninsula supported a light easterly to northeasterly airflow over the area. Showers and thunderstorms affected mostly northern and central areas on the 29th then spread to other areas of the country on the 30th.
In summary, on September 2nd the country experienced its first hurricane landfall for the 2020 Atlantic Hurricane Season, namely Hurricane Nana. The strongest winds occurred north of the storm’s center and the heaviest rainfall occurred south of the center in Corazon village, Toledo district where 144mm (5.7inches) was recorded. Although the country received some rainfall associated with Hurricane Nana and the passage of two tropical waves, the total rainfall recorded for September 2020 was mostly below normal. The graph and maps below summarize the total rainfall and average maximum and minimum temperatures. They also give an indication of how these readings compare to the normal for the month across the stations sampled. As can be seen, rainfall was below normal for most of the country except for Towerhill in the Orange Walk district that recorded slightly above normal rainfall. In terms of maximum temperatures all of the stations sampled show higher than average maximum/daytime temperatures while minimum/nighttime temperatures were above normal for all the stations except for Towerhill in the north and Punta Gorda in the south.Monthly Rainfall SummaryMonthly Maximum TemperaturesMonthly Minimum TemperaturesRainfall Observed: September 2020 (mm)Rainfall Observed: September 2020 (% Above/Below Average)
