1. The remnants of Atlantic basin Tropical Depression Nana are
expected to emerge over the eastern Pacific waters near the
Gulf of Tehuantepec late tonight or early Friday.  Unfavorable
upper-level winds are expected to inhibit significant development
through early next week while the system moves generally
west-northwestward, near or along the southern coast of Mexico.

Hurricane Nana Discussion Number   8
NWS National Hurricane Center Miami FL       AL162020
1000 PM CDT Wed Sep 02 2020

After the center of Nana nearly became exposed during the late
afternoon, a new burst of convection developed near and to the
south of the center which has resulted in strengthening this
evening.  Very recently received data from an Air Force Reserve
reconnaissance aircraft has indicated that Nana has become a
hurricane.  The plane has measured a peak 700-mb flight-level
wind of 72 kt to the north of the center, and peak SFMR winds
of 62 kt earlier this evening.  These data support an initial
intensity of 65 kt, making Nana the fifth hurricane of the 2020
Atlantic basin hurricane season.  Since Nana should make landfall
along the coast of Belize within the next several hours, little
additional strengthening is expected before the center crosses the
coast.  Rapid weakening will occur after landfall, and the new 12
through 36 hour intensity forecast reflects this.  The low-level
center is likely to dissipate over mountainous terrain within 48
hours, if not sooner.

Nana is moving just south of due west at about 265/14 kt. A low- to
mid-level ridge to the north of Nana should keep it moving on a
west-southwestward motion during the next day or so.  The guidance
enveloped has shifted slightly southward and the new NHC track
forecast has been adjusted accordingly.

KEY MESSAGES:

1. Hurricane conditions and a dangerous storm surge will spread
onshore along portions of the coast of Belize within the Hurricane
Warning area through early Thursday.

2. Tropical storm conditions are expected in the tropical storm
warning areas in Belize, the Bay Islands, Guatemala, and the
Yucatan Peninsula of Mexico through early Thursday.

3. Heavy rainfall with isolated maximum amounts as high as 8 to 12
inches could result in flash flooding in Belize, Guatemala, and
portions of southeastern Mexico and the Yucatan Peninsula.

颶風娜娜討論號8
NWS國家颶風中心邁阿密FL AL162020
1000 PM CDT星期三2020年9月2
日下午晚些時候，

娜娜的中心幾乎暴露在外後，
南對流爆發了新的對流中心，今天
晚上得到了加強。最近從空軍預備隊
偵察機獲得的數據表明，娜娜已成為
颶風。這架飛機
在中心以北測得700 mb峰值的飛行高度為700 海裡，而今晚
早些時候的SFMR峰值為62 kt。這些數據支持初始
強度達65 kt，使娜娜成為2020年
大西洋盆地颶風季節的第五次颶風。由于娜娜將
在接下來的幾個小時內沿伯利茲海岸登陸，因此
在該中心越過
海岸之前，預計幾乎沒有其他的加強措施。登陸後將迅速減弱，新的12
至36小時強度預報反映了這一點。低層
中心很可能會在48
小時內消散在山區地形上，即使不是更早。

娜娜（Nana）以大約265/14 kt的速度向正西移動。
娜娜（Nana）北部的中低階山脊
在第二天左右應使其向西南偏西運動。指引
包圍狀態已稍微向南移動，新的NHC跟踪
預報也作了相應調整。

關鍵信息：

1.颶風狀況和危險的風暴潮將
在颶風
預警區域內的伯利茲海岸部分地區陸續蔓延至週四初。

2.
到星期四初
，預計在伯利茲，海灣群島，危地馬拉和墨西哥尤卡坦半島的熱帶風暴預警地區將出現熱帶風暴情況。

3.個別最大降雨量高達8至12
英寸的強降雨可能在伯利茲，危地馬拉以及
墨西哥東南部和尤卡坦半島的部分地區造成山洪氾濫。
